I used to do RC racing, and since most of the material on the chassis is Titanium/Aluminum/Carbon fiber/Graphite, we need to use thread lock to secure every screw that is loosen before every run. The vibration will eventually loosen every screws on board if you are not careful.Nowadays, I only need it when it is for knife maintenance.
Never used it outside of a work environment. I have occasionally used wood glue or varnish to gum up threads a bit on threads I might wish to undo again later, or superglue when I wanted a more permanent fastening.
I think it depends on which loctite / thread locker you use. I use medium strength threadlocker (blue stuff) on my drone (DJI Inspire), primarily for the carbon fiber / polycarbonate propeller mounts that bolt directly on to the motors, I haven’t had any issues with them coming loose, and I have flown in some pretty hefty winds.From what I have experienced, the green stuff is the stuff that comes loose (not sure I get the point of the green stuff to be honest as it doesn’t seem to really do anything?).....the blue stuff (aka medium strength) doesn’t come loose, I have been using the blue stuff for years and I have not had any issues with it at least, and it’s fairly easy to undo the bolts/ screws again without damaging them.....the red stuff is basically like putting super glue on the threads, it’s close to impossible to break the bolts / screws loose if the red stuff has been applied, usually ends up rounding the bolt / screw heads off when trying to get them out.Sent from my iPhone using Tapatalk
I'm much more likely to use the "opposite" product:
