Thanks for the advice. Can't find mention of the HS-20 anywhere...? I'm looking at the HS-56BB instead. 16oz-in of torque, but based on the model number you use it sounds like it will be enough. I'll probably order that tonight :P

As for grinding the motor mount, I'm glad to hear someone has done it successfully. What pinion/spur do you generally run with? I thought I had a 40T spur but I was wrong, so I can't raise my gear ratio w/o attacking the motor mount.
