I like that idea. I had been thinking about adopting the 1.1" gun as a traditional single barreled aircraft cannon. My Gatling idea is for the 50. cal MG. The P-38 would also be a good mount for either 1.1" gun or either Gatling gun. P-70's and P-61's as well. Hmm, what about the P-39 and P-63?Near Fantasy desire?
