So exactly what do you have in mind for this setup?
I'm going to use the Monster Pro 125b in my E maxx outrunner setup with the 2 speed kit. (as soon as I can get it)
I'll probably go with a CC BEC so I can go 5S or 6S. It all depends on what the motor can handle and keep temps in check.
The ESC should be more than enough though.
I'm thinking about adding a Novak Cap to the power lead. These things have a TON of Zap and are really small.
