hi, I was one of the guys where traxxas sent me the upgraded castle spartan system, but I am having problems with it:

Im getting in start up, 6 blinks and beeps of green than normal red, red, green? And sometimes motor will go in reverse today for me but when i start up again, it sounds like its surging and does not move in reverse? Then I will stop throttle on transmitter, pushed it again and I will get full reverse power? then stop again and get this surging sound but no reverse again?
