For the money you might want to look at this for a esc.. SkyRC's Toro TS 120amp, I run this in 4 of my cars.. Other then a plastic case design it is damn good... I messaged SkyRC about updating the software for braking and about 3 weeks later there was a update... RCMART has them free shipping check it out...Small foot print..
