Well there is just not much to it, first read the book.
If the pirouette rate is not fast enough turn the limit setting on the gyro 20-30% higher. Yes it will bind the linkage but don't worry, doesn't seem to do it in flight.
Adjust your tail linkage so that your tail servo limit setting (on gyro) is over 100% NOT under. Setting the limits under 100% can reduce the life of the servo. Don't worry about the center setting just fly it in AVC or heading lock mode only.
Turn the gain up until it wags and back it off a little. This mostly occurs around 55-65% gain.
Also try the new 9254 servo it is faster and has more power...this is really a great help and seriously improves the gyro performance.
