This will increase the speed at which the tail motor spins proportionally to the main rotor and will
counter the tail's anti clock wise rotation.
If the tails want's to swing clockwise turn the setup/mixing screw counterclockwise, this will
reduce the speed at which the tail rotor spins proportionally to the main rotor.
The idea is to set the speed of the tail rotor just right so that the helicopters tail does not want to
rotate in any direction but remains neutral in flight.
If the mixing is not correctly setup the gyro will try to correct the tail too much. This will shorten
the life of your tail motor drastically. Take time to get it right.
Now flick the helicopters tail away from you, counter clockwise) The tail rotor should speed up
(rev) to try to prevent this movement. The "size" of this "Rev" is determined by the gain (control 2
)screw on the gyro. Do not fiddle with this screw, It should be set Ok.
Doing so will also affect the mixing ratio and you will have to start adjusting again from the top of
this chapter.
Now Still holding the helicopter, throttle up to hover rpm ( the heli wants to fly up out of your
hand). Feel again for any Forces exerted on your hand.
If there are no strong forces in the roll or yaw axis and the tail seems to be neutral, briefly let go
of the helicopter.
If you have setup your helicopter correctly it will fly (hover) pretty much in the same place you left
it. It may however climb upwards, in which case you must reduce the throttle slightly.
7 Service and Cleaning

Disconnect the battery from the Receiver and ESC.
