I don't have any pictures, but I'll give you a word by word of what happened.

So, first time I tried driving, the nut was too loose on the axle itself, which meant that when the motor span, the wheel fell off, which was slightly comical but it shown that it had promise. So I tightened it up and tried again.

Second time, and this was the failure point. It ran around for a good 5-10 seconds, then I saw the axle spinning around in the wheel. The nut was still attached to the axle... but the epoxy resin connecting nut to wheel separated so neatly, that it was just spinning in the wheel itself.

So I'm pretty much back to square one. When I can, I'll get pictures of it, but holy Christ this is quite irritating... I think the only decent option here for me without pulling out my hair is to buy some wheels from someone.
