Replacing The Blades; Fine Tuning Of Yaw Control - Merlin PULSAR 150 Manual De Instrucciones

Replacing the Blades

Your Pulsar 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 sufficient to make sure the blade still
moves freely.

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 :-
Gyro gain - the gyro detects rotary movement and will stabilise the tail automatically in flight. The Gyro gain dial
adjusts 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.
Throttle mixer - the throttle mixer is the balance between the two motors on the helicopter. When the throttle is
applied the mixer directs power to the second set of blades to compensate for the torque of the other motor and
blades. When this is in equilibrium and throttle is applied the helicopter will gain height without spinning left or right.
Clockwise will make the helicopter rotate to the right.
