personally I would not use locktite on any electronics - there is too great a chance that you will have to replace them between matches - they are all susceptable to failure from a number of causes - and when you need to swap them out, you need to be able to do it quickly.

if anything, put double nuts on and torque them into each other. You really cant tighten down the screws on the electronics or the plastic cases will crush.
