Hi neale.smith3191
The receiver might have a small screw which is marked "proportional".
Probably has + and - sign each side of the screw. This will determine how much % of power goes to the tail motor. Looking down at the heli if it is spinning anti clockwise you need to turn the screw to the +. If it spins clockwise turn the screw to the -. Only turn the screw a small amount at a time. You might also have to unplug the battery after each adjustment for it to have effect. Then you might need to reset the gyro gain.

I have had a look on youtube and it looks as if your gyro is adjusted by a knob on the transmitter. The proportional adjuster screw that outputs power to the rear motor will be on the receiver which is attached to the front of the helicopter. The receiver is the item the battery plugs into.
