The hilltronics switch didn't work , I put in a mod it works fine , but !!!!! The dam thing takes off full throttle runaway , and no steering, which is where I was at the beginning of this nightmare,,,,, I've replaced everything, completely stumped on this and completely frustrated, I would pay someone to help solve this problem I'm at the end of my evaluations, I just don't get it , I'm working with a futaba t4pm transmitter , if there's any master minds out there , ,, not kidding about paying for help , so thanks for your time guys
