8.2lbs is a little much, but still realy good with everything on it.
Are the gears steel or aluminum? Are there alternate gear ratios available?
I'm wondering if there's a way to remove the first stge of gear reductions without compromising anything. This could easily be made half a poun dlighter if that were the case.

EDIT: I can't see in the cad how the smaller bevel gear is constrained axially. Is there a shaft collar I'm missing?
DOUBLEEDIT: Same goes for the large bevel gear. It appears to only be constrained by a single e-clip and the wheel. And the wheel is not constrained.
