Alright I received the Rx-18 today and installed it. The functions in the lower hull are all working properly but unfortunately nothing is working in the upper hull. The machine gun and headlight only come on when I push the joystick to the right. Looks like matorro wired the upper hull completely different then heng long did. I will have to rewire it and connect the wires directly to each other. My question is what gauge wire does the heng long rx-18 use? I'm a little new at this so sorry for all the questions. Thank you John
