Instruction manual

The throle trim lever (located immediately to the right of the le-hand/throle sck) can be used to
adjust the throle control/channel output value for a given sck posion. For example, raising the throle
trim will make it possible to maintain altude with the helicopter when the le-hand/throle sck is in a
lower posion. However, we do not typically recommend raising or lowering the throle trim above/below
the middle/centered posion.
IMPORTANT NOTE: If you do raise the throle trim you
MUST remember to lower it to the middle/centered
posion AND the throle sck to the lowest possible
posion IMMEDIATELY in the event of a crash or rotor
blade strike. Failure to lower the throle trim to the
middle/centered posion and throle sck to the lowest
possible posion immediately in the event of a crash/rotor
blade strike can result in damage to the ESCs in the 4-in-1
control unit (which may require replacement of the control
unit).
Moving the le-hand sck to the le will turn (yaw) the nose of the helicopter to the le about the axis of
the main sha. This is accomplished by decreasing the speed/RPMs of the tail rotor.
