YHR you've been incredibly helpful thus far (don't think I'm close to done yet lol) I sincerely appreciate you taking the time. Hopefully I can pay back others in the knowledge that I've gained from you.

I do have a 3:1 gearbox on the way (with my replacement/spare RX18's), and according to what I've seen, it comes with black capped motors. I'd prefer to keep top speed somewhere close to where it was with the white cap HL motors (assuming the "white caps" are still the same in the StuG) but the gear reduction I think will be a bit more realistic in how it gets moving. Momentum would be fun, not quite ready to step up to that stage yet. I'm not going to drive this thing a ton, this is more about executing all the mechanical/electrical ideas I can come up with.

I've got a fan already, working on what I think will be a pretty nifty setup (waiting to see if my idea turns out as good as I think it will, before I publicize my project lol) just at a bit of a standstill when it comes to how I'm going to mount the fan/RX18. I may just end up removing the case from the RX18 and mounting the board on "studs" since the board has holes in it that can be used to mount it without the case, to make my cooling idea work. From what I've mocked up that will be the best option.
