No reply from mato yet about the problems, sent a 2nd email tonight. We'll see how they want to handle it, if at all. I could deal with all the little issues but come on 3-4' range is crazy! I actually have to stand over it to get it to work, and pray the machine gun sound doesnt stick. This is certainly not an enjoyable tank, at this point I'd take a HL Tiger over this. Might as well have a wire from the radio to the tank calling it remote control. Maybe a bad batch?
