Being a member of several RC sites, including being one of the admin here, I have read many posts about guys stripping out the hex heads of screws while trying to remove them. Sometimes the problem might be caused by a poor quality hex driver, but, I think the biggest problem is that most people seem to use, and tell others to use, "blue" loctite.
Being a truck mechanic at a Mack and Volvo dealer for nearly 2 decades, I use several different grades of loctite on an almost daily basis. The "blue" loctite was designed for use on 'medium-sized' fasteners, which most of our RC helicopters do not have.
I have been using the Purple colored "electronics grade" 222 loctite on my helicopters for quite some time now. I have not had any screws vibrate loose, but, they will come out much easier when you need to remove them.
The only place I use the blue stuff is on the main and tail blade grips as the bolts are under a lot of stress and I feel more comfortable with the stronger thread lock there.
If you are one of those guys that gets frustrated trying to remove screws that you put blue loctite on, give the purple stuff a try.
Keep in mind that all of my helis are electric , so the extra vibrations of a nitro might still require the stronger stuff be used on all of the bolts.
Just a little tidbit that might help someone out.
