For starters, go into Code 83 and reduce the rudder trim rate to 50%. This reduces the rate of yaw compensation the gyro sends to the rudder servo, without compromising any of the gyro's function or holding ability.
Next, make sure that you have the machine trimmed for hands-off hover in normal (non-HH) mode. Once you've got that, without distubing anything else, adjust the pushrod so that it and the servo arm are at ninety degrees to each other. Now switch to heading hold, get it up, and use Code 15 to tweak the tail rotor until you're back to hands-off hovering.
I'm setting up one of these right now on an X-Cell 30. I have heard quite a few complaints about this particular gyro not staying in trim, wandering, etc. But as I play with it, I think it is really nothing more than first-generation piezo technology; which means it IS going to drift some, but not enough to really gripe about. Nature of the beast with piezos; perhaps one day JR will catch up with whatever the new technology Futaba has been using in their 401, 601, etc.
I suspect that many of the complaints have more to do with improper set-up than any real problems with the gyro. For my sake, I hope I'm right...
