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.
