Never heard of anyone doing this, but in theory it could probably somewhat protect spur/pinion from debris coming from a certain direction - to a degree. I doubt it's really useful. Plus, with sensored motors (and their static end bell timing) there's no really useful way to reverse the whole thing. I simply bought a Tekno 1/8th scale buggy body as dust cover beneath the SCT body (damn truck is so heavy, those few grams didn't matter )
