I need to replace my tr belt. the problem is that I went a little too far with the thread lock. I used the blue stuff on the tr bearing collar hex head screws as well as the hex heads on the tr gear that is on the main shaft. they are stripped out and can't be removed. I tried to heat up the collar and gear to release the threadlock but the hex screws won't budge( key just slips).
question... does any one know how I can remove these without damaging the heli. thanks in advance.

Ralph,

I have used a drill bit that is slightly larger than the set screw (but not big enough to hit the threaded hole!) and then used a larger allen wrench pressed in there to pull it out.

use a little heat at the same time to warm up the locktite, Should do the trick

thanks I'll give it a try
