Well, I have ordered a pair of Graupner SPEED 400 7.2V Electric Motors from Hobby Lobby on the advice of this forum. So I did not want to take the chance of overheating with the more aggressive motors and frying something. I honestly do not know what motors are in my tank- I bought it with the metal gear set already in place. Or sort of in place- I had to disassemble and fit them properly to be satisfied. On both sides I had shafts jammed against the plastic body.... and all it took was 15 seconds with my Dremel tool to make a proper fit.

I've tried my tank and am really happy with the increase in power and the smooth action now. And it has power now- I tried to hold the output shaft while it was turning- no way I could stop it!
