Not at all, the FLUX tranny gears are known to wear down very quickly, even with moderate use- stripping pinions and spurs is par for the course too. I believe HPI have introduced hardend tranny gears now to address the problem, but the diffs can still wear out quickly, so people have been swapping them with the nitro equivelants which are more robust.
But ofcourse, only a noob wouldnt be aware of these things, right?...
