Hey guys,

I have a trex 450 se with the 401 gyro and 9650 and the Futaba 6ex fasst radio. The heli flys beautifully but I've noticed for some time now, when I'm in a hover, the tail will hold for about half a minute then the tail will move about 5 degrees to the left. I'll correct it with the trim, it moves back. I'll readjust the gyro, on the radio, and it moves back. My question is, do I have to readjust the delay or limit on the gyro its self? If so, which one?

thanks
