Hi,
I agree. I have shimmed my gearbox higher (.06") on my X-6 and so the diff gear is quite exposed. I have not made any guards and so far I have had no issue with anything getting in. I have raced on all extremes - dusty clay, sandy astro, mud, loose grass and indoors, with no issue.

I hope the damage was not severe, just an unlucky occurence.

I would suggest double checking all gearbox bolts, they do not like to be over-tightened - just finger tight, don't put any torque through, this may loosen the gearbox so it spins freely?
