Threadlock on motor screws with removable prop guards

[GeeDee]

I bought removable prop quards for my P3 and they require replacing the original four motor screws with longer ones. I noticed the original motor screws had a dab of blue threadlock, but I am nervous about using threadlock in case it causes some damage or I can't remove the screw (they are tiny). I am interested to hear what are others doing when they use removable prop guards.

Do not use generic threadlock, make sure it is safe for plastics.

Having said that I don't use any. Frequent inspection has yet to find a loose fastener.

Screws with blue thread lock, can be removed by gently heating it with a hair blower or heat gun, and then unscrewing the hardware. There are several grades of thread lock/lock tite that are used in the RC model industry. Not all are 'dead lock'... ;-)

Don't use it.
Not safe for plastics.

That's why the factory hardware uses cured TL

Simple trick when using thread lock with plastics... put a dab on the screw... let it dry first... then assemble.

The screw just needs a little interference in the threads so vibration doesn't loosen it over time... use sparingly.

Or use a dab of superglue. Works a treat
