Doing a Brushless Conversion. Advice Please.

[spiftacu1ar]

I used the rc calculator. I set it up with stock hpi stuff, and then changed the internal ratio to 2.5 (kershaw has 45t and 18t in the gearbox, 45/18=2.5). It said with my 13t pinion I would get to 36mph (big joe tires). You still think I should gear down?

Also, I already knew I was going to work in pairs regardless, I have 2 3s chargers (an mrc 977), so i can't charge a 6s anyways.

I also just realized I will also need to order some balancers. Do you have any suggestion for balancers compatible with the mrc 977?
