I'm not getting any barrel recoil. The tank was a Taigen scratch and dent. Recoil worked originally about 4 out of 10 times. I had been playing with the infrared switch and thought that might be the problem. I took the switch out and a little rewire about 6 months ago. Then disassembled for paint and detail. Now I don't remember the wiring. Everything else works.

I can trouble shoot. But I need to see the original wiring setup on infrared to check myself.

Does anyone have a diagram or good pictures of the connections?
