just curious what sort of issues ppl are having with Loctite?
if it ain't locking as it should... have they RTFM??
Threads should be degreased & loctite takes 4-6hrs to anarobic cure,
wipe threads with motorspray & i'll leave it unstresed for 24hrs if i can.
when at track... i don't bother with loctite for instant grab,
i use shoegoo (especially hot areas) or CA during pit repairs.
Loctite releases with heat, so even the red stuff is weak for engine screws.
Use a solvent type of loctite (gooey Tamiya Threadlock) or shoegoo.
Spillage? you can buy Loctite(tm) in a gluestick style
More often than not... its RC builders who have overtorqued your tiny screws
to beyond the metal's stretch point; when the shank is no longer elastic
the screw will never hold tight again & forever keeps backing out.
And take a tip from 1:1 cars... if there's screws that must never come out,
have a second mechanical way of locking them. Serrated or castlelated nuts;
for flat chassis bottom could be as simple as a strip of gaffertape or
scratchprotect film - stops all those flatheads moving until you want them to.
(when we build to 'enduro' spec, where its gotta last 3/4/5hrs not 6mins)
