Just received my mod yesterday and put the batteries in and screwed my Subtank mini to it. As soon as a connection is made it starts automatically firing!! Ever with it in locked mode as well. Tried taking batteries out and starting with screwing tank on first and then putting batteries in, same thing. Soon as a connection is made it starts firing. The tank is fine so that's not the problem. Switched back over to my mech mod (stingray x clone by HCIGAR) and it works fine. Does anyone have any clue of what's going on here? Bad DNA40 chip?
