I was also wondering about this gyro....read somewhere that vibration can render it insane.....adding foam double stick tape under it I read might help....
Darn thing just goes into a tail spin right at lift-off....

It will do that if the gyro is correcting in the wrong direction too. Even though you have the rudder servos operating in the correct direction, the gyro can still be correcting in the wrong direction. So make sure that the gyro is setup properly. The gyro should input right rudder when you rotate the helicopter`s nose to the left, and input left rudder when you rotate it to the right. Another possible reason, is that you have the gyro in rate mode, which will cause the gyro to not correct at all.
Foam tape is a good idea, or you can use two pieces of 3M outdoor mounting tape, which you can get at any walmart. Back in the day, we used to use gyro plates on our helicopters. A gyro plate is a small metal plate, that goes under the gyro. The plate was fixed to the airframe, and then the gyro was fixed to the plate. I doubt you can even find them these days though, but foam tape or two pieces of 3M will do the trick.
