Got a problem with my Vfc scar. Haven't had any trouble with it up to now. After a fresh charge I hooked up my 11.1 lipo and gun didn't fire on semi. Switched it to auto and it shot out 7 or so rounds then just stopped working. Doesn't make any sounds or anything. Just a dead gun. Was thinking maybe a wiring problem as I know the wiring in stock is kinda ****. Only other thing I can think is motor is shot. Bought the gun used and maybe fired 6000 rounds or so. Any suggestions? And if it is a motor problem is that an ex replace for a technically savvy dude?
