User Manual

Pay attention that the steered direction of your tail stick corresponds to the direction your helicopter should

turn. If this is not the case, use your transmitter‘s servo reversing function for the tail stick. If you‘re not sure

in which direction the helicopter should rotate consult the manual for your helicopter.

E Setting the Tail rotor endpoint

At setup menu point E you adjust the best possible servo throw for your tail rotor. This best throw is

determined by the maximum possible control travel of the tail mechanism or based on the maximum

allowed angle of attack of the tail rotor blades, that will not lead to an aerodynamic stall of these bla-

des. Such stalls can cause very bad stopping behavior.

To adjust the limits, move the tail stick in one direction until the servo reaches the maximum end point

without any binding or stall and release the tail stick. The further you move the tail stick the quicker the

servo will steer into the given direction. If you move the servo too far you can steer the stick to the

opposite direction and move the pitch slider a short way back.

Once you adjusted the maximum endpoint don‘t move the tail stick anymore and wait for the Status-

LED to ash and then light steady red or blue, depending on the adjusted direction. Now you have

saved the servo limit for one direction.
