You only calibrated the esc to the radio. You might want to check to make sure your endpoints are set to their max on the throttle channel while calibrating, might help. But with green light for throttle, that's right. I believe default settings are 75% reverse on the esc. Brake curve should be linear, and default brake setting I think is 100%, I usually end up backing it off to about 75% and it'll still lock up.

There are 3 settings for reverse, disable, delayed, and instant. Instant will reverse the motor as soon as the esc detects the motor isn't spinning. That means the truck can still be moving with the wheels locked (skidding) and itll go into reverse. In the delayed setting, the esc has to see at least one second of neutral throttle before engaging reverse, I like this setting best. It can be changed through the transmitter programming procedure, which I've never tried, but looks way too complicated for me. I'd live with it for a day until you can get a castle link, may end up making it undrivable if you mess up the transmitter programming procedure
