What is GyroBot 900 Wing? 

It is a world novelty. The GyroBot 900 Wing is a high-quality and precise flight control system 

with stabilisation of the aileron, elevator and rudder axis of a model airplane. Aileron, elevator 

and rudder ar controlled by the GyroBot. Thereby the flight characteristics of each plane will 

be improved of that effect that the model flies „like on rails“. A fully adjusted GyroBot 900 

Wing will always keep the model in the position you brought it to with the control sticks. But it 

never works against your inputs from the transmitter. The throttle function is not considered. 

This means for you: The model flies much better and more precise as without GyroBot, flying 

will be much easier. For example flying aerobatics is much easier because the GyroBot 

controls all „static“ figures itself after you brought the model into the right position. 

You must not switch on and off the GyroBot for doing aerobatic figures. You can fly the whole 

flight (except of the start and landing) with active GyroBot on all 3 axes (if you use an 

aerobatic machine). Figures like inverted, knife edge, hovering and torqueroll are completely 

controlled by the GyroBot. You only have to bring the model into the right position and then 

loose the stick (except of the throttle). 

During normal flight you only have to move the sticks if you want to change the direction or 

position of the plane, but you don´t have to do anything against restlessness of the plane or 

against wind impacts. GyroBot always keeps the model in the relative position, it does not 

orient itself on the horizon or on the cardinal points. 

GyroBot 900 Wing is not authorized for turbine powered Jetmodels!!! 

What is GyroBot 900 Wing Jet? 

GyroBot 900 Wing Jet is a version of GyroBot 900 Wing which is authorized for operating in 

Gas Turbine Jets. 

It is also authorized for all other kinds of model airplanes and it can be handled and 

programmed similar to the GyroBot 900 Wing. The only „disadvantage“ ist the higher weight 

and the bigger case. 

For flying Gas Turbine Jets you MUST use GyroBot 900 Wing Jet!!! 

Can I switch on and off the GyroBot during flight? 

Yes, via the flight phases. GyroBot 900 Wing has 3 flight phases which can be configured 

completely free. The control of each axis can be switched on or off during flight via switching 

between the different flight phases. For example if the control is off for all 3 axes in flight 

phase 1 and the control is on for all 3 axes in flight phase 2 you can switch between control 

off and on via switching between flight phase 1 and 2 during flight. For example you only can 

put on the control for the rudder (or elevator, or ailerons) in one flight phase.

4 ______________________________________ 

CAUTION: 

WITH THE ORDER OF THIS UNIT YOU INSURE TO US THAT YOU ALWAYS 

CONFIGURE THE FLIGHT PHASE 1 WITH COMPLETE CONTROL OFF FOR ALL 3 

AXES. 

(You can switch the complete control off in the particular „Tuning“ Menu for aileron, elevator 

and rudder). The big advantage of this measure is that if you configured something wrong in 

the other flight phases (wrong sensor direction of rotation or too high P and I values), you 

can switch back to flight phase 1 and the models flies like before without GyroBot. 

Please do also use the flight phase 1(control for all axes OFF) always for starting and landing 

as long as you are not very familiar with the system. 

Another reason for the basic necessity of a flight phase without any control is if there are 

sensor failures or errors for any reason, your model perhaps would become uncontrollable if 

the control of the GyroBot is on. In these cases you can switch back to flight phase 1 (control 

for all axes OFF) and your model can be controlled by you as if you don´t use a GyroBot. 

GyroBot 900 Wing does NOT know, if a flight attitude is right or wrong. If you bring the model 

into a vertical nose dive and loose the sticks the Gyrobot will also keep the model in this 

direction until it crashes. Furtermore it cannot work against the physics. So if there is a stall 

also the GyroBot cannot help. 

When should the control always stay OFF ? 

1. During approach and landing the elevator control should always be OFF, because with 

active elevator control a stall would not signalize itself before (the model does not take the 

nose a bit down like without control), but it would come very abruptly. The model would keep 

its attitude as long as the stall comes very abruptly. 

Thereforee please note the following: ELEVATOR CONTROL ALWAYS OFF DURING 

APPROACH, LANDING AND ALL SLOW AND LOW FLIGHTS WITH UNSUITABLE 

MODELS. 

2. During stationary stand or if the plane will be carried or driven to the starting point the 

control of all 3 axes should be off. (Please use flight phase 1 here). 

The reason is as follows: GyroBot only can work correct if the control circuit is closed i.e. if 

the plane can rotate around all degrees of freedom. This is not warrantied if the model does 

not yet fly. So the model could not follow the corrections of the Gyrobot and as soon as it 

would lift off it would make a short but very fast move (as long as the control circuit is 

closed). We want to avoid this „Moment of Shock“, so please don´t switch on the control 

before the model is in the air (as long as you are very familiar with the system). 

The right procedure for the start is as follows: 

If you carry or drive the model to the starting point, please always use flight phase 1 

(complete control OFF). During the start you can use a flight phase with only the rudder 

control ON, if you want. If the model is in the air, you can switch to a flight phase with control 

ON on all axes, if you want this. 

PLEASE DO NOT START WITH CONTROL ON FOR AILERON AND ELEVATOR !!!

5 ______________________________________ 

Which models are suitable? 

In principle all aerodynamical controlled model airplanes (no deltas and no models with V 

Tail at the moment) are suitable, but not a control of all three axes is ok for all kinds of 

models and for all flying attitudes. 

Here you find whats right or wrong for the separate model types. 

1. Aerobatic models: 

On 3D or Aerobatic Models the performance of the GyroBot can be practiced very good. With 

a flight phase with control ON on all 3 axes many very difficult aerobatic maneuvers run 

automatically. You only have to bring the model into the right position, then you can loose the 

sticks completely (except of the throttle) and the GyroBot 900 Wing will keep the model in 

knife edge flight, inverted flight, normal straight flight, hovering, torqueroll etc. 

So all “static” figures (figures which do not need any control for the figure itself, but only for 

keeping the model in this position) can be flow by the GyroBot, if you bring the model into the 

right position once. 

For example for the knife edge flight you only have to bring the model in the right position if 

you do a quarter roll and then lift the nose a little bit with the rudder, then the sticks can be 

released completely. 

Also very complicated figures like for example a horizontal knife edge eight is very easy now, 

because you only have to control the “eight” with the elevator stick, that’s it. No corrections 

of the rudder or aileron should be necessary. This schema can be carried to all other figures. 

2. Jets: 

CAUTION: 

GyroBot 900 Wing is not authorized for turbine powered Jetmodels, only for EDF Jets. 

For flying turbine Jets you MUST use GyroBot 900 Wing Jet!!! 

In slow flight and in approach for landing jetmodels often will be unstable and not easy to 

control. Special on the aileron axis jets often are instable. This will be avoided effectively with 

control ON on this axis. Control ON on the rudder axis makes the jet run very straight on the 

runway during the start. 

For large scale jet aerobatics or normal jet flying with enough speed control ON on all 3 axes 

is ideal. The model flies like on rails. Negative characteristics of the plane or wind influences 

will be corrected perfectly. 

3. Airplane Towing (Both Towing Model and Glider): 

Here you can use the GyroBot 900 Wing in both the towing plane and the sailplane. As both 

models fly straight with loosen sticks the whole aero tow flight steadies itself. 

For example it is also possible to “command” an angle of climb with the elevator stick to the 

towing plane which will be permanently kept. At will the control of each axis can be put on or 

off during flight. So the advantage is: Same speed during the whole towing on both planes 

and thereby also the cord is always tensed to the same level. 

If the aero tow is higher its more and more difficult to control the right position with the 

ailerons. With control ON on the aileron axes this is also no problem. 

In the glider during towing there should be an active control on the aileron axes, but not on 

the elevator and rudder axis. 

4. Gliders: 

Here you have to distinguish: 

In aerobatic gliders during the programm a control ON on all axes is good as long as the 

speed is high enough.

6 ______________________________________ 

CAUTION: If the speed is too low the stall comes very abruptly. If you want to avoid 

this, please switch OFF the control on the elevator axis. 

At thermalling in circle the control for elevator and aileron should be OFF, because otherwise 

the plane will not show you any more where the thermals are because it will no more “shake” 

the wings for example. Control ON on the rudder axis can be wise for continuous circles with 

the same diameter. 

If you use a Variometer also the aileron control can be ON. 

During straight flight between 2 thermal fields control ON on all axes could be useful, if there 

is enough speed. 

The same counts for F3B or F3F competitions. 

For all gliders counts: Elevator control OFF for the landing. (Stall!). 

5. For beginners: 

For the beginner it is a big easing to fly with GyroBot 900 Wing. 

A Trainer model with active control has no „live of its own“ anymore. Thereby the pilot must 

control only if he wants to change the direction. So flying a model airplane could become 

nearly as easy as driving a RC Car. 

Of course there are many more Types of RC planes which flying characteristics can be 

improved with the GyroBot. 

Installation in the model: 

Some important informations about vibrations: 

You always should fix the GyroBot 900 Wing with ONE ORIGINAL SELF-ADHESIVE 

PAD in the model. The GyroBot 900 Wing Jet can be mounted with one and a half Pad 

(in longitudinal direction one after another). 

In particular if you use large Gas Engines from 20 cc up to more than 250 cc which 

cause heavy vibrations it is VERY IMPORTANT that the GyroBot is fixed on a VERY 

SOLID BOARD which is connected VERY FIRMLY with the fuselage. The board MUST 

NOT swing or bend itself. 

The 1-2 mm thick boards in the AFR planes are UNSUITABLE. 

The board should be made from min. 6-8mm thick high quality plywood. 

In electric or turbine models it is less critical. 

The main unit of the GyroBot 900 Wing MUST be fixed PARALLEL to all 3 main axes of 

the plane. 

That means, it must be parallel to the roll-axis, to the pitch-axis and to the vertical (yaw) – 

axis. It should be fixed near the receiver and the power management system. 

The plug board of the GyroBot must look towards the front or the rear of the plane, but 

NOT to the left or to the right. 

It must not be fixed in the CG of the plane. 

Please ONLY USE ONE of the ORIGINAL double sided mounting pads which are included. 

Please fix it on a clean, smooth and stable surface which is solidly bonded to the fuselage. 

For GyroBot 900 Wing Jet you can use 1,5 Pads next to each other in the length direction. 

Please consider a good adhesion of the pad and the GyroBot.

7 ______________________________________ 

The following pictures show the right installation of the GyroBot in the model: 

Installation in an electric powered model 

Installation in a gas engine powered model

8 ______________________________________ 

Installation in a turbine powered model 

Never fix the unit bevelled to one of the 3 main axes. 

The pitot tube must be fixed on the tip of one of the wings and parallel to the roll-axis. 

It must NOT be fixed on the fuselage. 

You can fix it with a part of one pad between the wing and the tube and with 2 or 3 stripes of 

adhesive film. You also can glue it into the nose of the wing, but please think of the 20 mm 

distance as shown in the following picture.

9 ______________________________________ 

Now you must halve the 3mm Festo Tube and put the 2 tubes on the 2 brass pipes of the 

pitot tube. (If its too loose please use VERY LESS speed glue to safe them). 

Before you thread the tubes through the wing you must mark both ends of one tube with a 

permanent marker pen. 

Now please thread the tubes through the wing and pull them out on the root rib. In the 

fuselage the 2 tubes will be connected with the extension board as shown in the pictures. 

Please necessarily consider the right polarity. 

The tube which is on the straight brass pipe of the pitot tube must be connected to the upper 

pin on the extension board, the tube on the angulate brass pipe must be connected to the 

lower pin on the extension board. 

Connection Schema: 

The right place for the Extensionboard: 

Ideally the Extensionboard should be fixed with a part of one included pad in the fuselage 

near the GyroBot main unit. The position and direction of the board is equal. 

If you fix it in the fuselage, you must cut both 3mm Festo tubes and connect then again with 

the 2 Festo connectors. Then you only have to disconnect the Festo connectors if you want 

to remove the wing from the fuselage.

10 ______________________________________ 

To close the connection push the ends of the tubes tight into the connector. To open the 

connection you must push back the blue plate on one end of the connector and then pull out 

the tube. 

CAUTION: Necessarily mark the 2 ends of one tube before and after the connector 

with a piece of heatshrink (not too hot because of the tube) or colored adhesive film to 

avoid a permutation, otherwise the control does not work right. 

If it is possible, you also can fix the Extension Board into the Wing near the root rib. Then you 

only have to remove the servo connectors if you want to remove the wing. Then you don´t 

need the Festo connectors. 

If you fixed all parts correctly in the model please connect the GyroBot and Extension Board 

with the receiver of power management system. 

If you use a power management system (Powerbox, DPSI …) the GyroBot must be 

connected between the receiver and the power management system. 

If not, the GyroBot must be connected between the receiver and the servos. 

Therefore please use the following table:

GyroBot. 

Preparation/Programming of the Transmitter 

1. Choose a new model memory 

2. Switch off all Mixers 

3. Set ATV for Elevator, Rudder, Aileron to +/-100% 

4. Set all trims to center position 

5. Fix the 3 step switch for the flight phase switch and a control dial or a slider for the 

RC-Gain on the transmitter 

For your explanation: 

All servo travels, reverses, centers (for aileron, elevator and rudder) will be adjusted in 

the GyroBot now and no more in the transmitter. The agility of the plane can be 

adjusted with the servo travel (ATV) of the particular axis (for example if you want that 

the model makes faster rolls you have to increase the servo travel for the aileron). This 

counts for all 3 axes.

Declaration of the Flight Phase Switch 

Gyrobot 900 Wing offers 3 Flight Phases (3 Memories), which can be configured completely 

free. To switch between these 3 Flight Phases please connect the plug 7 on the GyroBot with 

a free plug on the Transmitter. Then you need a 3 step switch on the transmitter which 

switches this channel. You can see the current flight phase in the upper right corner of the 

GyroBot Display. A switching is only possible in the flying menu “System Running”. 

You always program the flight phase which you have choosen if you get into the 

programming menus (pushing the button a little bit longer, starting in „System Running“). 

Also during programming the current flight phase will be show in the display. 

You switch completely ALL values (all base and all tuning menus). Later you can copy the 

values from one to another flight phase in the “Copy Phase” menu. You always copy from the 

current phase to the phase you choose with the rudder stick. 

CAUTION: Please be sure that you have programmed (or copied from a programmed one) 

all flight phases. If you switch into a flight phase which is not programmed your plane will 

crash immediately. 

The agility of the separate axes will be adjusted with the servo travel (ATV, Endpoint) of the 

equal channel on the transmitter. 

For example if your plane shall fly faster rolls you have to increase the servo travel for the 

aileron function in the transmitter. 

Declaration of the Programming 

You can program the GyroBot 900 Wing either with the Cockpit Programming Box or with the 

USB Interface Cable and your PC or Laptop. 

If you use the Cockpit (which is the easiest and most comfortable way), you have to connect 

the Cockpit with the plug 1 of the GyroBot via the 70 cm Cable. Thereforee please put a 

10cm Patchcable (two servo connectors) into plug 1 and then connect this with the 70 cm 

cable. The other side of the 70 cm cable must be plugged into one of the both connectors of 

the cockpit, equal which one it is (minus/GND is on the side of the button). The 10 cm Cable 

can always be left in the model for later programming. 

If you use a PC or Laptop, please connect the USB Interface Cable to a free USB Slot on the 

computer and to the 10 cm Cable on slot 1 of the GyroBot. 

Now you must start and install the file “cockpit.exe” from your GyroBot CD. System 

Requirements are Windows XP, Windows Vista or Windows 7. 

Then look for the right COM port in the program and then push the ON/OFF button until the 

GyroBot Start Menu “System Running” will be shown. 

Therefore the GyroBot must be connected and under voltage from your receiver battery. 

If the software does not work please install the following driver. 

http://www.ftdichip.com/Drivers/CDM/CDM20802_Setup.exe 

The driver is needed for using the USB Interface Cable, in newer Windows Versions it should 

not be necessary.

14 ______________________________________ 

The programming is the same with the Cockpit or with the PC and will be handled as follows: 

Navigation through the 

menu >>> 

Adjustment of Values >>> 

Cockpit 

Programming Box 

Button 

Rudder Stick on 

the Transmitter 

PC and USB 

Interface Cable 

Space Bar on the PC or „Menu“ 

button in the PC Cockpit Programm 

Rudder Stick on 

the Transmitter 

Every value is saved automatically if you leave the menu. 

For rudder, elevator and aileron there is one base menu and one tuning menu. 

In the base menus you can adjust basic settings like servo travel (ATV) etc., in the tuning 

menus the values like P and I gain will be set. 

The menu „Calibrate“ is used for reading the center positions of the transmitter and save 

them in the Gyrobot. In the “Check it” Menu nothing can be set, it shows you if the sensors, 

inputs etc. work right. In “Model type” at the moment you only can adjust “Standard”, later 

there will be more models types available. In “Copy Phase” you can copy the setting from 

one flight phase into the others. 

Programming of the GyroBot 900 Wing 

Now please take your completely assembled and installed plane and connect the GyroBot to 

the Cockpit or USB Cable. Then switch on first your transmitter first and then the receiver 

with the GyroBot. 

Caution: As long as the GyroBot „boots“ you MUST NOT move the model or the 

GyroBot. The system is booted if the green LED shines and if „System Running“ is 

displayed. 

On the GyroBot 900 Wing Jet you cannot see and LED, here you MUST NOT move the 

model as long as the servos make a short movement into the center position. 

PLEASE ALWAYS CONSIDER THIS, OTHERWISE THE UNIT WILL NOT WORK RIGHT 

DURING FLIGHT. 

Now switch into flight phase 1 with your 3 step switch on the transmitter (1 must be displayed 

in the right upper edge of the display). 

Choose your language 

Now press the button and keep it pressed. Now choose your language with the rudder stick 

and then loose the button. 

1 Calibrate 

Now you are in the menu Calibrate. Please press the button again, now you see “release the 

sticks and press the button”. Now loose all sticks and center all trims on the transmitter. Now 

press the button again. Now the GyroBot has read the center positions and saved them (but 

only for the current flight phase). 

Now you are again in the Start- and Flight Menu “System Running”. 

Important Information to Calibrating: 

Always if you change settings on the transmitter or the GyroBot the last step before

15 ______________________________________ 

flying again should be „Calibrate“. 

Please always calibrate all 3 flight phases ! 

2 Model Type 

Push the button a bit longer again and loose it then, now navigate to the menu 

Model Type with the rudder stick. 

At the moment you only can choose the mode type “Standard”. This is a normal plane with 

cross-tail or t-tail. Further model types will be available later via software update if customers 

wish them. 

Push the button again short, now you are in the menu Vibration Filter. 

Leave this value set to 1 at the moment. The Filter is important for models with gas engines 

which cause heavy vibrations. It will be set later. In electric or turbine models this value 

mostly can be left at 1. 

Push the button again short, now you are in the menu Servo Frequency. 

Now choose the right frequency with the rudder stick. If you don´t know it, please always 

choose „Standard“. Modern Digital- or Brushless Servos should be driven with „Speed“ or 

„High Speed“, but we cannot guarantee this. 

The rule of thumb is: If the servo runs smooth and does not make any abnormal sounds, the 

choosen frequency should be possible. 

We cannot guarantee that the servo does not get damaged. If you are not sure please 

choose „Standard“. 

Push the button again short, now you have done all settings in the menu Model Type and 

you are in the menu System Running again. 

3 Rudder Base 


Rudder Base with the rudder stick. 

Push the button again short, now you are in the menu Rudder Servo Centered. 

The rudder servos will be driven to the center position and you can adjust the rod or servo 

horn, if you want. 

Push the button again short, now you are in the menu Rudder Servo Center. 

Now please move the rudder exactly to the center position with the rudder stick. 

If the servo direction is wrong, please reverse the rudder channel in the transmitter and then 

set the rudder exactly to the center. 

Push the button again short, now you are in the menu Rudder Minimum. 

(This can be the left or right maximum position). The rudder automatically moves to the 

direction which maximum will be adjusted now. Now adjust the maximum position with the 

rudder stick. 

Push the button again short, now you are in the menu Rudder Maximum. 

(This is the other maximum position). The rudder automatically moves to the direction which 

maximum will be adjusted now. Now adjust the maximum position with the rudder stick. 

Push the button again short, now you are in the menu Rudder Gyro-Direction. 

Here you can reverse the effective direction of the rudder gyro, if this is possible.

16 ______________________________________ 

Please do it as follows: Rotate the model around the rudder axis (vertical axis), the rudder 

must work against the rotation. If this is right, everything is ok. If this is wrong, please reverse 

the effective direction of the rudder gyro with the rudder stick. 

CAUTION: The effective direction and also the servo reverse must be absolutely 

correct for all 3 axes, otherwise your model will surely crash. 

Push the button again short, now you have done all settings in the menu Rudder Base and 


(If the rudder is not exactly in the center now, please calibrate and repeat the setting Rudder 

Servo Center once more). 

4 Rudder Tuning 


Rudder Tuning with the rudder stick. 

Push the button again short, now you are in the menu Rudder Control. 

Because we program flight phase 1 at the moment (Control OFF on all 3 axes), please 

switch it OFF now with the rudder stick. 

(For your Information: Control "Off" means the complete control is off and the model flies like 

without GyroBot). If control is Off the following menu items will not be displayed. 

Push the button again short, now you have done all settings in the menu Rudder Tuning 

and you are in the menu System Running again.

Adjusting and reducing of the rudder travels 

Please read this very watchful 

Now we adapt the servo travels (ATV´s, endpoints) in the transmitter for rudder, 

elevator and aileron. Therefore we act as follows: 

The GyroBot is in Flightmode „System Running“ in Flight Phase 1, we start with the 

rudder:

19 ______________________________________ 

If you move the rudder stick now it is possible that the rudder is in maximum position 

as soon as the stick is not yet in maximum position. The stick has a “deadband” 

Now reduce the servo travel in the transmitter (for both sides) as long as the rudder is 

in maximum position when also the stick is in maximum position. 

Then repeat this for aileron and elevator. 

With the servo travel you also adjust the agility of the plane. At the moment you have 

adjusted the maximum agility. 

Is the model too agile on an axis, please reduce the servo travel for this axis in the 

transmitter (for both sides) as long as the agility is ok for you (you only can check this 

during flight). 

If you want to reduce the agility right now before the first flight then please reduce the 

servo travels for all axes as long as you think the rudder travels are ok. 

Now you have done all settings of flight phase 1. 

Please calibrate once more and get back to “System Running“. 

Now please copy flight phase 1 into flight phase 2 and 3. 

Please do it as follows: 

10 Copy Phase 


Copy Phase with the rudder stick. 

Push the button again short, now you are in the menu Copy Flight Phase. 

In the upper row you can read: 

From [1] 

For the second row please select: 

To [2] 

with the rudder stick and press the button again. 

Now you have copied from 1 to 2 and you are again in “System Running”. 

Now push the button a bit longer again and loose it then, now navigate to the menu 

Copy Phase again with the rudder stick. 

Now please select: 

From [1] 

To [3] 

with the rudder stick and press the button again. Now you have copied Flight Phase 1 into 2 

and 3. 

Now we will program Flight Phase 2: 

GyroBot is in „System Running“, please switch into Flight Phase 2 with the 3 step switch on

20 ______________________________________ 

the transmitter. In the right upper corner of the display you must see a 2. 

For our example now we want to program an aerobatics model with control ON on all 3 axes. 

This is only an example and can differ from your interests or models. 


Rudder Tuning again with the rudder stick. 

Push the button again short, now you are in the menu Rudder Control. Switch this “ON” 

now with the rudder stick. 

Explanations to the P and I Part 

The GyroBot 900 Wing „learns“ and optimizes many things itself during flight, but the P and I 

part must be adjusted by you. These both values are available for each axis. The P part 

makes the model stop hard and “crips”, if you loose the stick or better stop the stick 

movement. The I parts makes the model keep its position as good as possible. For a perfect 

control you always need both values. Please adjust them always to the same level. These 

both values together are the “Gain”. 

For example: If P for the rudder is on 150 I for the rudder should also be on 150. If you want 

to increase the Gain for the rudder, you have to adjust P to 175 and I to 175 for example. 

(A separate adjusting of the P and the I part is possible, but it only should be done by pilots 

who are very familiar with the system.). 

The main principle of the setup is always the same and it works as follows: 

During flight the values (P and I always together and at the same level) will be increased as 

long as the model locks „crips“ and is absolute stable if you loose the sticks. 

The values are too high, if the model starts to swing at any time of the flight. The values are 

correct, if the plane is just under the border to swing. 

Now we return back to Programming: 

Push the button again short, now you are in the menu Rudder P. Set the value to 150 now. 

(If it is not yet displayed). 

In the 2. Part of this menu you can switch on and off the RC-Gain. 

Explanations to "RC-Gain" 

RC-Gain means that you can adjust the particular value during flight via a control dial or a 

slider on the transmitter. If „RC-Gain“ is „off“, the controller on the transmitter is inactive for 

this value. If RC-Gain is „on“, you can adjust this value during flight. 

In practise it is reasonable for respectively one axis to switch on the RC-Gain for the P and 

the I part and then adjust it during flight. After having finished this axis it is very important to 

switch off the RC-Gain for both values of this axis, otherwise it will be displaced again if you 

fly and adjust another axis. Now you can switch on the RC-Gain for both values of the next 

axis and adjust this one during flight. 

You should do this for all 3 axes. As soon as you switch off the RC-Gain the values are 

saved in the GyroBot. 

The controller works as a “incremental encoder” (the same as the volume controller of 

modern hi fi systems). 

Now we return back to Programming:

21 ______________________________________ 

We are still in the menu Rudder P and we already have set the P part to 150. 

Now we want to switch on the RC-Gain for the P part. Therefore we push the button and 

keep it pushed as long as the display refreshes and the value moves from „off“ to „on“. Now 

we can loose the button, RC-Gain for the Rudder P is on now. 

Now it is displayed: 

RC-Gain: On 

in the lowest row of the display. 

(In the same way we can switch it off again later). 

Push the button again short, now you are in the menu Rudder I. Set the value to 150 now. (If 

its not yet displayed). 

In the 2nd Part of this menu please also switch ON the RC-Gain for the I part. 

Push the button again short, now you are in the menu Rudder Deadband. 

The Deadband is a small range around the center of the sticks where the GyroBot does not 

receive any signals. In most cases the default setting will be ok. You only have to increase 

the value if the servos move away from the center position if you don´t move the sticks. 

This can happen if the potentiometer in the transmitter is not the best. Please calibrate first, if 

the problem is still here please increase the deadband in 20 point steps until its ok. 

Push the button again short, now you are in the menu Rudder Airspeed. 

Explanations to "Airspeed" 

With Airspeed we mean the measurement of the current aircraft speed via the pitot tube and 

the airspeed sensor in the extension board. 

This measurements will not be show in any display but they are needed for a perfect control 

in all speed ranges. The software is very complex here because the aerodynamics aren´t 

linear to the airspeed but there are very special interrelationships between many terms. 

You must not know anything about that but you can benefit from all this by a perfect control 

through all airspeed ranges. Therefore “Airspeed” always MUST be ON. 

Because the control is very sensitive if the plane has no airspeed (for example during the 

torqueroll), a shiver of the servos is absolute normal if airspeed is on and if the plane stands 

still. 

You can check this if you press your finger onto the front of the pitot tube. Now you create a 

pressure and the Gyrobot thinks the plane is flying… 

The shiver must reduce now. 

Now we return back to Programming: 

We are still in the menu Rudder Airspeed. Please switch this “ON” now with the rudder 

stick. 

Push the button again short, now you have done all settings of Rudder Tuning and you are 

again in “System Running”. 


Elevator Tuning again with the rudder stick. 

Push the button again short, now you are in the menu Elevator Control. Switch this “ON” 

now with the rudder stick. 

Push the button again short, now you are in the menu Elevator P. Set the value to 150 now. 

(If its not yet displayed).

22 ______________________________________ 

In the 2nd Part of this menu please switch off the RC-Gain (because we first want to set the 

rudder during flight). 

Push the button again short, now you are in the menu Elevator I. Set the value to 150 now. 

(If its not yet displayed). 



For the last two values of this menu counts: 

Leave the Deadband on 30 and switch the Airspeed “ON”. 

Push the button again short, now you have done all settings of Elevator Tuning and you are 



Aileron Tuning again with the rudder stick. 

Push the button again short, now you are in the menu Aileron Control. Switch this “ON” now 

with the rudder stick. 

Push the button again short, now you are in the menu Aileron P. Set the value to 150 now. 

(If it is not yet displayed). 



Push the button again short, now you are in the menu Aileron I. Set the value to 150 now. (If 

it is not yet displayed). 



For the last two values of this menu counts: 

Leave the Deadband on 30 and switch the Airspeed “ON”. 

Push the button again short, now you have done all settings of Aileron Tuning and you are 


Now you have prepared flight phase 1 and 2 for the maiden flight. Flight phase 3 is a copy of 

flight phase 1, with control OFF on all 3 axes. 

We will suggest you once again that this is only an example that can be used for aerobaticsor 

3D models on which a control of all 3 axes is useful. 

If you wish to control only the aileron of your plane for example, of course you have to adapt 

the settings accordingly. 

Explanations to "Trimming with GyroBot 900 Wing" 

Please pay Attention to this text component. 

Trimming of the rudder, aileron and elevator with GyroBot is different to trimming of a normal 

model so it needs special explanations. 

If the control is OFF on an axis you can trim it the same way as without GyroBot.

23 ______________________________________ 

If the control in ON on an axis it MUST NOT be trimmed anyway. 

The reason is the Gyrobot cannot differ between trimming and moving the stick so it „thinks“ 

that you want to change the angle of the plane (you want to control it). 

But that’s not yet the problem, because controlled axes do not need any trim. 

The problem comes if you switch between flight phases without control and with control. 

For example: You Fly in your model in flight phase 1 (all controls OFF) and trim it as long as 

it flies straight. 

Now you want to switch into another flight phase with some controls ON. These axes will 

start moving away now because they “think” you want to control. 

The problem can be solved in 2 ways: 

The first one is as follows: 

1. You trim your model in flight phase 1 (all controls off) completely and land again. 

2. Now you switch into flight phase 2 (with controls ON) and calibrate this one. You also 

can do this for flight phase 3 if you also want to use this. 

3. FROM NOW ON YOU MUST NOT TRIM ANYMORE. 

The disadvantage is: You cannot trim in the meantime, otherwise you have to repeat the 

procedure. 

The second way is much more comfortable, but it needs a transmitter with a phase trim: 

1. You use the same switch on the transmitter for flight phase switching on the GyroBot 

AND for trim switching on the transmitter. 

2. Then you can trim the flight phase without control at any time and as often as you 

want. The flight phases with control have their own trim phases (not trimmed) and 

everything works fine. 

The maiden Flight 

CAUTION: The red printed part is only important for gas turbine models: 

In gas turbine models you MUST use GyroBot 900 Wing Jet. 

Furtermore you MUST arrange the following tests: 

Switch on the transmitter and the receiver and don´t move the model until the GyroBot 

has booted completely. Connect the Cockpit or your USB Interface Cable and the PC 

and navigate to the menu „Check it“ and the Sub Menu „Gyrosensor“. 

Here you can see the 3 sensor movements in a bar graph. If the model stands still, 

nothing must be displayed here. 

Now please fix the model, start the turbine and drive it slowly through all rpm levels. In 

the meantime please watch the bar graph very watchful. There must not be displayed 

anything at any time and at any rpm level. 

In other words the bar graph must display the same as if the turbine is off and the 

plane stands still. 

Repeat this test 2 or 3 times. If there is absolutely nothing displayed, everything is ok. 

If you see some (or also only one) bar, you MUST not start. You must fix the GyroBot 

on another place in the model as far away from the turbine as possible. 

Then please repeat the test.

24 ______________________________________ 

YOU MUST NOT FLY, IF THIS TEST HAS NOT BEEN PASSED ABSOLUTELY 

SUCCESSFUL. 

CAUTION: The blue printed part is mostly important for gas engine models: 

Gas engines from 20cc up to more than 250 cc cause heavy vibrations which can 

influence the correct control of the GyroBot. 

There are 2 things to avoid this problem: 

1. A very stable mounting board as described above. 

2. The Vibration Filter in the Menu “Model Type”. 

The board is a basic requirement! 

Now act as follows: Switch on the control and airspeed on all axes and set all P and I 

values to min. 300 (only for this test). 

Now fix the model, start the engine and drive it slowly through all rpm levels. 

Check all rudders (rudder, elevator and ailerons) during the whole time. Does no 

rudder move or travel away everything is ok and you don´t have to change anything. 

If the rudder or elevator or aileron moves you have to increase the vibration filter in 5 

point steps as long as no rudder moves or travels away during all rpm levels. If you 

found the right value please repeat this test 1-2 times. 

One thing is also very important: The Vibration Filter not only filters vibrations but it 

also makes the control of the Gyrobot worse if its set too high. 

Therefore for this setting counts: Do not set the vibration filter higher than absolutely 

necessary. 

And don´t forget to set the determined value in all 3 flight phases. 

YOU MUST NOT FLY, IF THIS TEST HAS NOT BEEN PASSED ABSOLUTELY 

SUCCESSFUL. 

We come back to our example of the aerobatics or 3D plane. 

After having switched on the transmitter first and then the receiver and having not moved the 

model until the GyroBot is fully booted, we will check all gyro and rudder directions and 

center positions again. We are in flight phase 1 and all rudders must be in center position. 

If we switch to flight phase 2 all rudders also must stay in center position. 

During flight all axis are controlled in flight phase 2, but we only can adjust the rudder via the 

RC-Gain. 

All gains are relatively low so we think that the model will not swing but it will be not crisp on 

all axes with these gains. It should respond spongy and indirect. 

If you have checked everything, please start NECESSARILY IN FLIGHT PHASE 1 (control 

OFF on all 3 axes). 

Now please adapt yourself to the different reactions. If the agility is too high or too low you 

can adjust this with the servo travel on the transmitter. If everything is ok, please bring the 

model into a straight and horizontal flight and switch to flight phase 2 then. 

Now you can adjust the RC-Gain for the rudder in very small steps (always only one step on 

the control dial or a slider of the transmitter). You have to increase the RC-Gain (higher 

values) as long as the plane is “crips” if you loose the sticks (with “crisp” we mean the model 

should stop abruptly if you loose the stick). Then the setting is ready. 

If the model reacts very “crisp” from the beginning or even swings you must lower the RC- 

Gain until the swinging stops.

25 ______________________________________ 

If the settings for the rudder are done please switch back to flight phase 1 and land (please 

DO NOT move the RC-Gain controller in the meantime). 

Now we connect the Cockpit Programming box or the PC and we switch RC-Gain for 

Rudder P and Rudder I OFF. 

Now the gains for rudder are saved. 

Now we do the same for aileron (one flight) and elevator (one flight). 

The setup is finished if all (controlled) axes are „crisp“ and very stable if you loose the sticks 

and the model never swings in any flight situation. 

Caution: Never adjust the gains too high, because this can cause a swinging of the 

model which can destroy the plane. 

This procedure is only an example and can be changed from you as often as you want. 

9 Check It 

In this menu nothing can be adjusted, but you can check several values. 

Push the button again a bit longer and navigate to the menu Check It with the rudder stick. 

Push the button again short, now you are in the menu Inputs. Here you can check all inputs 

from the transmitter. After calibrating the values should be between +/-10. 

Push the button again short, now you are in the menu Extension Board. 

Here you see first the signal of the Airspeed Sensor. It should be around 0 if the model 

stands still. If you press your finger into the cone of the pitot tube or blow into it the value 

must increase (with prefix +). If it decreases (with prefix -) you have exchanged the 2 festo 

tubes. 

The pitot tube always must be clean and dry. 

If this function does not work correct, you must not fly (the control would no more be 

as perfect as otherwise). 

In the next line you see the input of the RC-Gain controller on your Transmitter. 

The third line (Throttle) is not used at the moment. 

Push the button again short, you are now in the menu Gyrosensor. 

If you move the model, you can see how the gyros work. 

If the model stands still, there MUST NOT be displayed anything. Otherwise perhaps 

you have moved the model during booting of the GyroBot, please check this. 

If booting is ok and nevertheless there are some bars seen, you MUST NOT fly 

(perhaps a sensor is damaged). 

Push the button again short, you are now in the menu Accelerometer. 

Here you see the 3 coordinates of the accelerometer. It is normal that the Z value is around 

350 because of the gravity.

26 ______________________________________ 

Installing Software-Updates 

We want to keep your GyroBot always up to date. Therefore you can update it yourself if 

there is a new Software (Firmware) Version. 

Before updating please note all settings you have done. Normally the values stay stored but 

we cannot guarantee this for the future. 

Download the new firmware file „gyrobot.bin“ (or similar) from www.lf-technik.de and save it 

on your harddisk. 

Connect the GyroBot and your PC via the USB Interface Cable. 

Copy the file „flasher.exe“ from the Gyrobot CD to your harddisk and start it with a double 

click. System Requirements are Windows XP, Windows Vista or Windows 7. 

Now choose the right COM port and click on the button „load“. Now browse to the file 

“gyrobot.bin” and load this via a double click. 

The window should look similar to the following picture now: 

Now click on the button “flash” and AFTER having done this connect the GyroBot to the 

receiver battery during the next 10 seconds. 

The transmitter is not needed for the update, but it should be switched on because of the 

safety. 

If everything works right, the green bar graph should start. After the graph is finished, please 

wait 10 seconds and then remove the voltage from the GyroBot. 

If the update does not work, please install the following drivers: 

http://www.ftdichip.com/Drivers/CDM/CDM20802_Setup.exe 

and 

http://www.microsoft.com/downloads/details.aspx?displaylang=de&FamilyID=0856eacb- 

4362-4b0d-8edd-aab15c5e04f5 

If there are any problems with the update, do not fly and repeat it or contact us. 

Please check all values before you fly again.
