X3V screw glue or not?

I have a couple of X3V but have not been using screw glue on them. I had a issue with the screws for the swagarm to the mid-connector. Tried screw glue - but think I put on to much glue - and the screw broke inside the mid-connector - impossible to get out. New midconnector has been mounted but the screws were not in the screws package. Should be M1.4x10.

In the manual it does not tell if we should use screw glue on these screws.

I naturally have to check and thighten the screws regularly.

Someone also told me that on as thin as M1.4 screws - the glue is not neccessary.

But I also see that many says - always screw glew. (Metal to metal of course)

Any "best practice" on screwglueing the X3V?

Thanks
Stein

I use "blue" (medium strength) Loctite 243. Not so strong so as to not be able to remove the screw, but strong enough to lock them in place for flying.

Thanks..

I used 222 - low strength

243 - medium strength

So i think 222 is the right one to use on thin screws. But i did not apply any heat to the screws before taking them out - and i know i applied to much glue as well.

Ah, nice guide... thanks for that. You definitely need to be sparing with the loctite, as you definitely don't want it getting into any of the bearings! Regardless of what strength you use, on the swagarm screws, just a tiny drop into the "out" end is enough, let it sink in a bit then wipe away the excess, remember to run the screw in and out a few mm a couple of time to spread it a bit as well. Not to far out or you run the risk of getting loctite in the swagarm bearing! Once the screws in place, wipe away any excess again. I've not had any issue's doing it this way and the screws are still removable without excessive force. I guess if you use 222 you'd run less risk of fracturing the screw when removing it though.

With regards to your old mid-connector, get a 0.7 mm drill bit into your drill or drill press and drill it out from the "in" end of the hole. This way the rotating force of the drill will also push out the left over screw. Once it's out then use some solvent to clean out the remaining loctite & thread. I've had to do this myself when one of the tail fin holding screws sheared on a hard landing.
