Brushless MT2 Questions.

You'll get a good runtime with a 4600 on 6~7 cells, but your speed will be below 40 mph. If you are only going to use 6~7 cells, I'd get a 5700. It should get you over 40 mph, but the runtime will be a few minutes less. I think you'd still get 15 minutes with IB4200 cells.

If runtime is your primary concern, get the 4600, but if you'd rather have more speed than runtime, get the 5700.
