Thunder Tiger Raptors 30-90 - Imperio > Tail way too sensitive

My Raptor30 tail is way too sensitive. I barely give it some rudder and it just spins like crazy in one direction. Then I give it some opposite rudder and it spins like crazy in the other direction. I have turned the sensitivity pot all the way down on the Helimax HH gyro - and it still didn't help. I checked that the belt is turned the right way and the tail rotor is spinning the correct direction. What's weird is that the only thing that helped (very little though) is to change my ATV for the rudder on my JRXP652 radio all the way to 150% (range is 0% to 150% for each direction of the rudder). Not sure what is going on here. Any help would be appreciated.

Turn down the atv on your radio. This gives you more a selection of rudder travel per % of stick. Otherwise with a little rudder the tail blades will move alot with small input of stick. eg with only 50% atv the tail rotor pitch will (or should be) approx 30% of the same movement of what you have at 150%atv.
Make sure your not binding the tail slider either. With that much atv it could be stalling the servo. The exception is if you are using a super short rud servo horn which you shouldn't be using with hh gyro. Check you gyro instruction again.

Hope this help.
Sorry if you already know this stuff.

I actually turned my ATV's all the way down to 0% and the problem didn't get any better. Still spins like crazy in either direction. Perhaps a bad gyro?

Your gyro could be reversed. Make sure that the gyro is inputting the opposite input against the direction of yaw rotation. Inputting right rudder should cause the servo horn to move forward, correct? So if you spin the helicopter counterclockwise (left), the correct heading hold gyro input would be a clockwise counteraction, or a "right" input.

Hold the heli by the blade grips. Make sure you are in heading hold mode. Input left rudder to get the blades to stay at the left extreme. Now spin the heli counterclockwise, and watch the linkage. The gyro should input an opposing movement, and pull the linkage forwards, in affect inputting a "right rudder" input.

Hope this makes sense.

Thanks, John Cadwell

Your gyro is reversed. Just flip the reverse switch on the gyro and try it again.

Gyro Reversed

I had the same problem, try reversing the gyro, what was happening was the gyro was trying to stop the yaw by inputting more yaw rate in the same direction!
