So I bought a used heli and I go to take it apart and check everything and just about every Damn screw is stripped...after a couple hours me and my dremel finally got all out and replaced...I couldn't believe the amount of loctite on the old screws....

It's pitiful, all you need is a little medium loctite when it's metal to metal. I had a heli once, I had to use a heat gin and vice grips to get some screws out. Good luck...

I got them all out ...reverse drill bits didn't work...in welding Allen wrench on didn't work...what did work was the last thing I tried...I was worried about doing this because I didn't wanna mess the carbon frame up but I didn't touch the frame...a little slot in each screw and a flathead screwdriver I they came out..some were a bit tough but a few hours later all hardware replaced..

you can use a soldering iron to heat up the fastener and the loctite just melts away.

It is for some people foreign territory and have not worked with small screws until getting a model.

I am finding, depending on the model, that not all screws going into metal actually need Loctite at all.

I am sure I will be flamed for this statement but I have found very few screws actually need Loctite. And after I assemble a heli even fewer.

Now don't get me wrong, if 'one' screw will bring the heli down it will be Loctite'd but such as frame screws one screw backing out will not bring the heli down. And after Loctite has been installed on a screw some times I will not apply any more. We are trying to keep screws from backing themselves out. There isn't someone up there with a driver removing them. If a screw has been tightened properly and the heli is relatively vibration free AND the screw is not a critical fastener, it will probably stay in place.

Also some people apply to much loctite. The best way to apply the Loctite is to place a drop on a slick surface, and roll the first thread or two in the puddle. I see threads about removing Loctite and feel if they didn't use as much they wouldn't have to worry about removing the excess. Remember we are using loctite to keep the screw from backing ITSELF out not from being turned by a driver.

I know some will disagree but my helis don't fall out of the air because all the screws have backed themselves out.

I sprayed a head once with wd40 and that same day I lost several screws in flight.

So draw your own conclusions.

I had a training video for ultralight / gyrocopter engine building. (Rotax Jet ski motors) Even on 3/8 inch dia bolts, you only put a single drop of blue locktite on them. A drop is actually a LOT more than really needed for the little bolts.

I put loctite where the manufacturer wants it, and use a very small amount. Rebuilding after crashes (many) taught me that.

I made a mistake once, but I was wrong?

Heat gin...

...is what you apply to yourself before considering using wd40 on screws you dont want to lose.

Or after losing screws. Either works.

pipe thread compound works best, non-hardening & screws won't loosen even in high vibration areas

Interesting. Revmix, you have a brand name of pipe joint compound ? i get it at a discount at work.
