Wow. That's quite an impressive battery you've got there too. 120A is a lot of amps. So, you've got the power of a horse that's been taking steroids, on a three or four pound motorbike
That should be interesting.
I agree, it's not a big outlay to try different motors. I've done the same with planes, and have ended up with boxes of spare motors. I'll never live to use them all but I don't regret the expense. Some of them will get used, the rest are there if I ever need them.
