when I gas the servo it works fine when I fit the break, it spins into reverse mod opening the carb all the way...it will not get out of this mod until I hit the gas again...got any ideas....? THANKS

so your saying your servo only goes one way,even when you push the trigger forward???

goes foward, but when I fit the break it spins into opening the carb wide opens & to get it out of this mod I need to fit the it gas again....

I'm not sure I quite understand your problem/question. Is it that the servo is moving the wrong direction when you hit the brakes? It is opening the carb instead of closing it and applying the brakes? If so, you need to reverse the channel on your radio.

...or is it that maybe you have a stripped gear when you try to apply the brakes?

The controller is ok??
