sounds like you need to reverse the gyro or the rudder. Spool up the heli till it gets light on the skids and check the rudder direction, ie move the stick right and see if the nose turns right. If the rudder is moving the nose correctly, flip the switch on the gyro the other way. Should fix your problem.

really depends on the set up, how much throw, what arm your using, placement of the link in the arm, etc. I fly mine on a 9303 and it's set around 60% gain. If it's really twitchy then start backing the gain down till it stops hunting. Your real close if you can do a pirouette and stop without the tail moving back and forth.

fill me in, what's going on, still the same problem or something different? Have you tried adjusting the gain values in the tx yet?

401

I have my throws at stock and my gyro set at 68% and 49% and it stays pretty steady. I also use the full size servo that comes with the gy401 combo, I acutally had this on a 50size fueler, but the little extra weight don't seem to bother it.
