To help you solve your problem, I have to understand exactly what the problem is. When you say you can't "get the drive motors to work" what does that mean? Do they not move at all whatsoever? Do they move but not in the way you expect?
Having a brake option on the ESCs will definitely cause issues with turning and transitioning from forward to reverse. So you need to disable the brake mode or buy some ESCs that don' have brake or have the option to turn it off. But even with speed controllers that have brakes, the TCB can still send a signal to them and you should still see your drive motors turn. If you are getting absolutely no movement whatsoever then you have some other problem - perhaps you haven't specified ESC as the Drive Motor Type, or maybe your radio setup didn't complete properly, or maybe you have the ESCs plugged into the wrong RC output, or who knows.
Watch the
red and green LEDs on the TCB. Do they indicate forward and reverse movement? If not check your radio setup. Note also that you need some function to start the engine before the TCB will even begin to move the motors.
