Operating instructions

Pre-flight adjustments:
Caution: disconnect the motor wires from the speed controller to avoid the motor bursting into life unexpectedly, as this could cause
injury. Note: all the model's components are correctly set up at the factory, and no adjustments are normally required. However,
screws, pushrods or cables may have worked loose or suffered damage due to the long period in transit.
Swashplate adjustments:
Checking the swashplate
Caution: disconnect the motor wires from the speed controller to avoid the motor bursting into life unexpectedly, as this could cause
injury. Place the helicopter on a level surface. Move the throttle stick and throttle trim to the bottom position (throttle off), and set the
trims for pitch-axis, roll and tail rotor to the centre position. Switch the radio control transmitter on, then connect the receiver power
supply. The receiver LED will glow constantly, and the servos jerk, to indicate that the transmitter signal has been picked up. Please
check now that the swashplate is straight, i.e. exactly in line with the tail boom.
Caution: disconnect the motor wires from the speed controller to avoid the motor bursting into life unexpectedly, as this could cause inju-
ry. At half-throttle (throttle stick central) the servo output arms must be horizontal (parallel to the servo case), and the swashplate should
be in the centre of the collective pitch travel. If the swashplate is not straight, you can use either of the following two options to correct it.
1. Adjust the output arm on the servo: disconnect the battery from the receiver, and switch the transmitter off. Unscrew the output lever
from the servo. Now switch the transmitter on, and connect the receiver power supply. When the initialisation process is complete, fit
the output arm on the servo at 90° to the pushrod, then fit the retaining screw to secure the output arm.
