Ran it with 4600mah 7 cell with 17/90 gearing. Ummm, WOW!
It is for my son and I wanted to bump him up a bit since I'm running VXL. Tomorrow I'll test extended runs for heat and see if I can get some video. I'm actually wishing I had gone with the 17 turn instead. Might need to gear this down a little. It is much quicker then stock! If this orion motor can handle 8 cells like I've read in other posts, I'd say it is faster then the VXL with stock gearing. Not the same acceleration of course but plenty fast.
