Well I figured it out, the issue was not with the Clark board, but with the instructions. The instructions show cannon and MG1 on channel 9 and gbs on/off and MG2 on channel 10. They are actually reversed. Since I don’t have the gbs module or a 2nd Mg I did not put put channel 10 into my transmitter. When I originally tried to fire the gun I was hearing the gbs on/off sound and MG2. According to Clark the programming mode starts at the default settings when you program. Hopefully this can be helpful to someone else. -Ryan
