If it's screwed into plastic it doesn't need locktite but metal to metal does. I use blue on everything else

What does blue locktite signify @bjay415 ? Medium?

 

I use three, mainly the blue, for bearings, the red bearing retainer, and for things that really have to stay together, Red

I only use red on the tail and head spindles while everything else metal I use blue.

Better look out for @Crash Heligod!!. If you're referring to the Loctite brand the colours are purple (lowest strength), blue, red then green. If you need red on an electric heli I hope it's a bolt you can lean on with a big spanner! Loctite 262 (the red stuff) is stud lock & designed for things like engine inlet manifold studs.... think about that for a minute & it's no wonder you can't get a small screw or bolt out, that stuff is strong!
Have a look here for an application guide http://www.loctite.com.au/aue/content_data/133403_LT_4985_Threadlocking_Users_Guide.pdf

The Loctite brand is slightly more powdery (if that is such a word) than alternative brands such as Lynx and the like, i prefer the loctite brand as i find it easier to loosen bolts without striping. I have been around long enough to know how much to use and how hard to lean on a bolt.

 

Metal to metal loctite 242. Into plastic I have been known to apply a little CA

I just follow the manufacturers instructions, where it says to use Loctite I use, where it doesn't, I dont.

But yes, once Loctite is used in plastic, it can render it useless, as if its metal on metal, you can get a lighter to loosen the parts.

In fact I just used a lighter on the Loctite between the tail shaft and tail housing on an SDX.

I dont know if the Loctite burns / melts, or the metals expand due to heat causing the Loctite to loosen, but it worked.

 

Loctite will loosen when heat is applied

I use the glue set which is supplied with the TSA kits. It works very well, and I have yet to have a screw back out on any of my helicopters. The green bottle, is the thread locker for metal on metal connections, and the other two bottles are two part epoxy. I use the epoxy to seal the pressure nipple on the fuel tanks for added prevention of leaks. The small packet is silicone grease. On plastic parts, I use a dab of CA on the end of the screw before running it in. For loosening thread lockers, I have found that a 30 watt soldering iron, applied to the head of the screw for 15-20 seconds works like a charm.

 

Nice...Good information there @Geena. Do they have locktite in America? If not what brand do you use thats generic?

 

Do they have locktite in America your funny.

 

Oh yes! We have the locktite brand here, as well as a couple of generic brands. Like Zap Z-42 Blue. I have a couple bottles of the blue Locktite brand and the Zap brand in my toolbox. They both work about the same, but the Zap is a little cheaper.

 

Ahhh ok cool. Thanks @Geena. And @5Fidy I dont get out much. Only to fly helicopters....lol

 

Getting out to fly helicopters, is the best reason to get out.
