Default problem: screws backing out of multaple parts

ok so my issue is that on my rustler containing both traxxas and rpm parts i keep having screws back out after a pack or two, one is for the right front camber link which is stock plastic mounted to the stock tower the other issues are the front right a arm at the bulkhead the arms are rpm and use the screws to hold them, i have tried a brand new pair and same issue, the last area is the left rear arm screw on the tranny bulk head keeps backing off/out. i did get some advice to flip the screws around to the reverse position this is untested but i was willing to try it and see. i was also thinking maybe a dab of locktight or ca glue? im looking at changing to adjustable links once the stock ones break at that point i can just utilise longer screws and some lock nuts. was just looking if anyone had any other ideas. thanks all

I have used a drop of CA glue numerous times with success on different things.

blue threadlock is your friend. Non permanent but will hold if you allow it to dry. IMO CA glue is not a good idea.

I really like this stuff called Vibra-tite. It's more gummy than gluey, and treated fasteners can be adjusted/dissassembled/reused multiple times without reapplication. Seems spendy, but a little goes a long way.

Used to use it on single cylinder dirt bikes which will spit out fasteners constantly if you don't stay on top of it.

This is a common problem with all the traxxas RC's I've owned. I just check everything after each run. Good maintenance habits.

The hinge pins screws can be turned around (did that on my own when I had a slash).

Can use ca glue, works best.

Can use blue locktite. I found this doesn't work as well in plastic.

Use longer bolts and put a locking nut on the end.

Use hinge pins with e-clips.

Def more than one way to handle your issue...

use blue loctite on metal to metal, and ca on metal to plastic parts! but beware that if u dont let the CA dry on the plastic parts before u insert the screw, u will strip out the plastic threads when ever u decide to remove the screws! on plastic let the drop of CA puddle in the hole a little, then when its dry the tolerances will be tighter for a greater hold on the screw without ruining anything when u decide to replace something.
