Looks sweet. Nice job!!

Only thing I see that I would worry about is how close the pinion gear is to the lipo pack. A nose down landing and that front tab on the battery box could bend and let the lipo contact the pinion gear. A spinning pinion will make short work of the lipo. If you can extend the front side of that battery box so there is no gap in front of the pinion gear and the lipo would be protected from the pinion in a worst case scenario.

Sweet job. Looks like it nice clean layout.
