i don't have the losi but this is just a question as i have a friend building one, i have heard the issue of the piston screw coming loose if you don't let the lock tight dry, but that could cause problems if your rebuilding at the track, so my question is, could you maybe red locktight in a long grub screw and use a nylok nut like the other cars or would that cause a problem with the bladder, thanks guys.
