Hi marked23,
I'm Zanasi's Friend, and I just talked with him by the phone. I will try to explain what he is trying to say. I don't understand about heli, I will just try to translate what he is trying to say.
He told me that his heli turns(Spins in itself using the tail blade) more to the left than to the right. And normaly (RC Airplane) you can configure this in the radio. But because the servo in the tail is connected to the gyro you can't. So you have to configure in the gyro amplifier.
And that is Zanasi's Question:
How to configure that, so he can equal the turning ability in the gyro amplifier?

Thanks
