In case you are using a single-line receiver, note that in the first menu points of Receiver Menu no control signal is emitted on the throttle output([CH5] or [DI1]). Only at Menu Point N (Throttle failsafe setting) the output will be activated to check throttle position! If you use a speed controller with BEC, disconnect the motor to avoid unintentional starting of the motor! For a heli with combustion engine you should remove the servo horn from the throttle servo to avoid linkage binding or breaking the servo horn.
