I think that attaching a servo directly to the pot, although not as clean looking, will be the less troublesome method. I might even have to spend a few dollars and get a better gyro, but if what I'm trying to do works, it will be worth it, at least for me.
I'm going to put the receiver for the pan unit on my helmet along with the gyro. Then I'll simply run a servo lead down to the tx and either mount the servo internally if I can or move the pot somewhere on the tx to mount the servo to.
I'm just about done moving so by wed I can start the tinkering process.....
I've heard about drift with using a gyro, but doesn't the control surface go back to neutral without any input? That would mean if it started drifting all I'd have to do is hold my head straight a second or two.
