The rudder is the vertical control surface on the tail fin and is mostly used on take-off or landing as it
works very well at low speed. The control surface is activated using the left hand stick on the transmitter
side ways. In flight when you push the stick to the right it will cause the model to yaw to the right rather
than rolling. Pushing the stick to the left will create the opposite effect.
On the ground use of the rudder will help to keep the model travelling in a straight line. If you push the
stick to the right it will cause the nose of the model to turn to the right.
With maximum stick movement you want to have 15mm of rudder movement each way.
This is the control for the amount of power available from the motor. Pushing the left hand stick forward
will increase the power and pulling the stick back will reduce the power. The stick is on a ratchet so you
can set a cruise power and the motor will stay at this setting. Be very careful of rotating parts as they can
be very dangerous, electric models make very little noise so the effect of the propeller catching something
is often more damaging than expected.
Throttle control in flight is very important and often ignored. The altitude (height) of the aircraft is
controlled as much with the throttle as it is with the elevator. By increasing the throttle the model will climb
and gain altitude, by decreasing the throttle the model will descend. With experiment and practice you will
be able to set the throttle stick at a position that will give you a straight and level flight.
The throttle stick should always be in the fully closed position before plugging the battery in.
Never leave the model unattended when the battery is plugged in.
