On my electric FTX carnage i have noticed that sometimes when i put the throttle on full it just cuts out? OR will go into reverse and stop? Also at random times the car will make a single quick beep and the engine will stop working.It sounds like it could be because of low battery but it never used to do this and sometimes does it mid way trough battery life?

Any help would be greatly appreciated!

Thanks.<br type="_moz" />
