Before the First Flight (continued)
If you are not familiar with the controls of the helicopter, please take a few minutes to familiarize
yourself with them before attempting your first flight.
The left-hand stick controls both throttle (ascend/descend) and rudder (yaw left/right). When the throttle is in
the lowest position the main rotor blades will not spin. Advancing the stick upward will increase the speed of
the main rotor blades. Increasing the speed of the main rotor blades will cause the model to ascend.
Decreasing the speed of the main rotor blades by lowering the stick will cause the model to descend. After
lifting the model off the ground you can balance the throttle so that the model will hold a stationary hover
without ascending or descending.
You can also use the throttle trim to adjust the throttle value for a given stick position. For example, raising the
throttle trim will allow the model to hover at a lower throttle stick position.
