I just put a Flysky system in all of my models. I tried to calibrate the ESCs, and it worked fine on all of my older VXL 3s vehicles, but not on my new 4TEC or 1/16 Revo (VXL 3M). I press and hold the ESC button till it turns from off to green, then red. It flashes red once, apply throttle, flashes twice, then apply brake. At this point, it should flash green until brake is released, then go solid green. However, it does not. I get no light at all after applying brake, it just stays off. Any help would be appreciated.
