Hi again Rowesteel:

I am assuming you mean that the tail is trying to spin around with the machine, as opposed to the tail rotor is spinning (or slipping) on the tail rotor shaft??

If the tail is trying to do circles with the airframe, I would suspect you have a gyro adjustment or trim problem. If the tail rotor is slipping on the tailrotor shaft, you may have loose setscrews holding the tailrotor hub to the hollow shaft. (OR stripped tailrotor servo gears if you may have had a crash or two)

I fly a Corona, electric version of yours, which has an electronic gyro, so I'm afraid I can't be of any help with the Arlton mechanical gyro.

Stand by for a bit, and some of the 110 experts like darthdrk, spiro or others will come to your rescue!

Good luck and Happy Choptering,

Russ
