I have noticed that a few of frame bolt holes are stripped. Could this be because I used loc tite or just over tightening, which I have found I have done a lot of.
Is there a way to fix the stripped ones that anybody knows about? I do have some stuff that is for plastic that is like putty that will bond to the plastic that I was going to try and re-run the screws through.

I AM ADDICTED, NOW WHAT

First, don't use locktite on plastic, it won't do anything. Only use locktite on metal to metal connections. You usually do not need anything on screws that go into plastic.
You want the screws snug, not overly tight, the holes probably stripped from overtightening.
Use some thick CA on the screws and it will be fine.

Or..

The blue Tamiya loctite for use on plastic.. That won't hurt the plastic.

No locktite didn't cause the problem. Overtightening did. As was said locktite will not do anything where plastic is concerned. If I am at all concerned about a screw going into plastis I usually put a dab of medium CA on the tip of the screw, and I then install it. It serves the same purpose in this applecation.

Build it, fly it, crash it. Repeat as often as needed.

I've had CA hold a little too well, so I use white glue (Elmers) for all screws in plastic. Works great.

I CA in screws on the rotorhead that go into plastic parts, and I learned no to use loctite. Some people told me that the loctite will eat away the plastic, but I don't know if thats really true. It doesn't really matter though, as it won't help you either way...

The plastic frame posts on my Raptor stripped out after a while. Overtightening is BAD, but expect plastic parts to strip eventually. They don't last forever. I bought the metal frame post set so they wouldn't wear out as fast, saving myself the trouble of taking the whole heli many times.

Loctite can make the plastic brittle.

This is from the loctite site:

I used Threadlocker on a metal bolt and a plastic nut. Why didn't it stick?

Threadlockers should only be used on metal-to-metal applications, because the Threadlocker turns into a plastic-like substance.

But experience shows loctite does also make some plastics go brittle or soft. So it should be avoided.

Infact this loctite site states:

To avoid stress cracking or attacking of thermoplastics, a superbonder or cyanoacrylate can usually prevent this problem.

The problem with cyanoacrylates is when the screw is removed from the plastic it tends to destroy the threads in the plastic. Not good.

Tamiya thread lock (Item: 87004) works great if you are concerned about a screw into plastic.
