Well, yeah, that's what everybody says. What I did was, I slid my hand palm-down under the heli on top of the skids so I could hold it down when I spooled up and, sure enough, the tail servo drifted toward the tail. I pushed the rudder stick to get it centered and when I let go, it drifted again.

I hate to sound so dumb, but how do you switch back & forth between headlock and rate mode? Is that where I plug the sense wire into my receiver or not? That's kinda what that pigeon-Chinese-English manual sorta says, I think. In the SUBTRIM section of my DX6i, there's RUDD & GYRO. What's the difference?
