502x / 511 universal drive pins falling out!

[cs8sz]

Hi,


I seem to be having major problems with my 502x with the drive pins which hold the axles and the universal shafts together, no matter what I do the grub screws always loosen and the pins fall out. I always assemble them completely dry no grease, and use Losi thread lock which I found to be the strongest around, but they fall out. This maybe due to the 502x being shaft drive and causing more strain. It seems a rubbish design as the new Tamiya 417 touring car has clips over the pins which prevents this whole issue, and I wish that they would do the same for the buggies.


Anyway what does everyone else do to hold the pins in? I am tempted to just use super glue!


Thanks for your help
Chris
