I tried to instal a 1268sg high voltage servo in my Associated B4 and the ESC wont initalize. If I plug the servo in after the Mamba Max Pro initalizes it goes to about 1/2 throttle and the servo still doesn't work or throttle. When I unplug it, the throttle stays for about 5 seconds the returns to neautral. I have tried 7v setting for the Castle Link. When I plug another servo in,it works fine. Any ideas?
