Thanks everyone. If I add the yellow to the blue the result will be green. Sailor ed look at props that are spinning and tell me they don't look blurry to you. I guess the shutter speed of my camera is the same as the human brain. I will try a render with the yellow and see where it takes me. Parkled the cannon are on the side of the fuselage under the cockpit and wing root. They may be mach guns, but I think they are 20 mm cannon.
