Turning around the vertical axis (curve):<br />

rudder and aileron (in basic version:<br />

rudder and V-shape of the wing<br />

Turning around the longitudinal<br />

axis (banking or turn): aileron or V-<br />

shape of the wing if rudder is<br />

activated<br />

longitudinal axis<br />

vertical axis<br />

Turning around the lateral<br />

axis (up - down): elevator<br />

lateral axis<br />

Free axes of revolution: In contrary to a car<br />

or a ship, the <strong>Skydreamer</strong> is controllable at<br />

all axes (3D) as soon as it moves in the air.<br />

Changes in attitude and flight direction are initiated<br />

by movement of the control surfaces (rudder,<br />

elevator, and aileron).<br />

Power switch: Transmitter and receiver are<br />

each equipped with a switch to turn on or off<br />

current supply.<br />

Propeller (airscrew): The propeller is driven<br />

by the motor and generates the propulsion of the<br />

model. The power of the motor, size and weight of<br />

the model and resulting air speed, determine the<br />

design of a propeller. The better the propeller is<br />

matched for a model, the better the efficiency and<br />

flying performance. There are two important<br />

dimensions that determine a propellers<br />

performance. Diameter and pitch preferably<br />

indicated by the inch. The propeller of the<br />

<strong>Skydreamer</strong> with the values 5x4,5 (inches)<br />

has a diameter of 5and a pitch of 4,5 inches;<br />

during one rotation this would make a forward<br />

movement of 4,5 inches for one revolution. If<br />

rotating at 8,000 rpm that would result in approx 34<br />

mph. The speed which can be attained is slightly<br />

lower as the propeller can generate propulsion<br />

only with a certain amount of "slip".<br />

Receiver: The receiver intercepts the signals of<br />

the transmitter via its antenna and converts them<br />

into pulses for the servos which operate the control<br />

surfaces. In addition it converts the radio signals<br />

for the electronic speed controller which regulates<br />

the speed of the electric motor according to the<br />

position of the throttle lever on the transmitter.<br />

Receiver and speed controller are already installed<br />

into Your <strong>Skydreamer</strong>.<br />

Rudder: The rudder of most airplane designs<br />

utilise at least one fin, preferably in a vertical<br />

position with a movable flap at the end. By<br />

swinging the flap to the left or to the right, affects<br />

the airflow which moves the tail of the airplane<br />

sideward. Together with other effects (V-shape of<br />

the wing or operating the here optional ailerons)<br />

the rudder starts turning the airplane.<br />

Servo: The steering signals of the<br />

transmitter are converted by the<br />

receiver into control values for the<br />

allocated servos. The servo motor<br />

operates the servo lever by means of<br />

a gear, which then moves in an arc<br />

according to the signal, up to 1/6th of a circle.<br />

Usually the servo lever is connected via rods to the<br />

control surfaces.<br />

Speed controller: The electronic speed<br />

controller regulates the speed of the motor with<br />

almost no power loss, by switching the motor<br />

current on and off (with a very high frequency) in<br />

differing long pulses. If the voltage of the battery<br />

drops by continuous discharge below a certain<br />

limit, needed to operate the servos, the speed<br />

controller will stop the motor. Your<br />

<strong>Skydreamer</strong> remains controllable in a<br />

power off glide.<br />
