Wheel pants, colors and prop
Andy:
When NR718Y was modified for the 1933 National Air Races, adding the big engine, bumped cowl and swept windshield, all of the openings in the wheel pants were faired over. Photos taken before the fatal race show this quite clearly.
Jim:
According to "The Gee Bee Racers" by Mendenhall, both of the "Y"s were red and white with a black pinstripe. This book may be wrong, but it was the primary source of PAMs scale info during the design of the ARF.
Jimmy:
Try a 16x6 Master Airscrew Classic on that G23. Ours works very well in the Gee Bee now that it is fully broken in.
