What should I do?

Yeah, I was trying to fit my 600xl into my rustler tonight, but it is too fat to fit in the narrow hole... I was thinking... pick up a zippy 4s pack and run that in rustler with the 9920 in the rustler with the vxl motor

If you can squeese a 427ci hemi into a Volkswagon bug, you can squeeze that motor in there. There are many creative ways to make a square peg fit into a round hole, if you just think outside of the box.

Wont work. BK's have a 42K RPM limit with 2-pole motors. I learned the hard way. See, like I said- "ridiculously small RPM limit".
