Fine Tuning of YAW Control
The controls are pre set in the manufacture and test flying of your helicopter and should not need adjustment.
However for tuning by experienced pilots or in the event of a serious crash and the need to re-build your helicopter
their adjustment and function is as follows :-
Left / Right Bias
- adjusts the speed of the tail turning between left and right to achieve equal response to control
inputs. To increase speed of movement to the left turn the adjuster clockwise a small amount.
Gyro gain
- the gyro detects rotary movement and will stabilise the tail automatically in flight. The Gyro gain dial ad-
justs the sensitivity from 0 - 100%, the best setting is around 90% as pre-set. When the setting is too high the tail will
be seen to wag from side to side, making it unstable. Adjust the dial to compensate. Clockwise will reduce the
amount of gyro gain.
Tail Rotor Trim
- if when hovering the helicopter tail drifts more than can be corrected by the transmitter trim levers
then adjust the tail rotor trim to achieve a stable flight. Adjusting the trim clockwise will add right turn.
Replacing the Blades
Your Polaris helicopter is supplied with a spare set of replacement blades in the event of crash damage. Should you
need to replace the blades please follow these simple steps :-
1.
The blades are fastened with a screw and can be removed very easily
2.
Loosen the screw on the damaged blade and remove it allowing the blade
to come off
3.
Insert the new blade into the gap and replace the screw tightening only suf-
ficient to make sure the blade still moves freely.
Receiver and Servo Wiring
Under normal circumstances there should be
no need to unplug any of your receiver wiring,
however for reference purposes the receiver is
wired as follows.
