You are running the Got2GoRC combo ?
Its just a rebadged Ezrun 35A ESC (with ext bec) and tweaked pulso motor unless it has changed recently
They retail for $122 dont they ? Hardly a bargain
Who told you it had better FETS that were made in the USA ?
Adding those FETS make the ESC capable of running a 6000kv motor on 3s ?
