I think it is crazy this was even attempted. The hazard of delayed firing is extreme, and there were so many other obvious solutions to the problem. Probably the sanest fix is to put the guns out on the wings. Firing through a center hole is possible, with the propeller on a hollow shaft. Pusher aircraft don't have the problem. Twin engine aircraft don't have the problem.
