Good job on finding the crossed motor wire. I recently got my revo conversion going and have only messed with it for about 10 min. The MMM and medusa 60mm 2000kv seemed good, but I'm wondering if I too crosses motor wires and forward is revese and vise versa. I have it set for 50% reverse, but when I tested the ESC on my test bench in rev the thing took off violently. Forward seemed good, but I'm not sure if thats just becasue I don't know any better. lol.
Anyway get that drive shaft fixed so you can beat on that monster some more.
