I run both 1/10th scale (losi XXXNT) and now 1/8th and have been told to never use loctite on plastic.

CA glue works (just a drop) as does tire glue. I found out about the tire glue when racing one day and a shock srcew backed out of the front A arm - the quick fix was tire glue and it worked well. AND - when it came time to remove the screw (to rebuild the shocks) it came out easily! Much cheaper than a new A arm!!!
