The 3PK and 4PK have something called "ATL". I'm not sure what that stands for, but is your brake percentage. I have it bound to one of the wheels on the grip, which is probably how it comes. That way I can adjust real quick and easy.

I'm not sure if the 3PL has that option, but there's more than one way to skin a cat. Calibrate your ESC at 100% throttle and brake EPA, then simply turn down the brake EPA to whatever you want.
