Just opened up a brand new xmaxx 8s..... Charged two new 4s lipo batteries, installed in truck and have a truck that is completely whacked. Steering will work, have no forward or reverse (other then a random twitch of throttle in the wrong direction) steering starts wondering all over the place on its own. When I hit the throttle the green light goes out for a split second on the esc then comes back on. Does this every time in forward or reverse. Been out of RC for a while, all of this crazy electric stuff has me Puzzled. Any help would be appreciated! 🍻
