Also how short are your motor wires? I thought I read something in the instructions that say the motor leads must be XX" long. Give castle a call, those guys are top knotch. I had a similar problem with a mamba in a mini inferno, turns out the settings were wrong, and the guy I talked to even gave me his own personal set-up from his mini. I run mine in a TC now, and It feels better than the GTB I used to own.
