TRF502x Gearbox screws keeps coming loose

[Netmav]

Hi guys,

I've been racing my TRF502x (first RC car I've ever raced) for a while now, and I've noticed an issue with the small countersunk screws that help secure the front and rear gearboxes to the chassis of the car (I believe they are M3x6mm, if my memory serves me right).
They come loose quickly, and when they do, they strip the threads in the plastic immediately.

Since the gearboxes are made from plastic, ordinary threadlock compund (Loctite 243) won't be of much help. So, has anyone else experienced this problem, and what have you done to overcome it?

I could of course retighten the screws after each battery pack, but I really don't want to do that, as it requires the undertray to be removed, in order to get access to the screws.

Is there some sort of "plastic threadlock" available, that would solve this problem? I really don't want to use ordianry CA glue, as I need to be able to remove the screws at some point, to service or change parts..

Thanks.
