Vintage N number location
« on: September 27, 2016, 09:00:22 PM »
I'm starting the finish on the Chambers R-1 I'm building for the "Tuscon" 1/2a scale contest. I can't find any photos showing the bottom of the wing. Would the N and race number be on the bottom of the wing as well?

The race number on the lower wing is in question. It doesn't show in any photos I have been able to locate. The N number is most likely there, but no photos show the lower left wing. Also, there is a dash between the 5 and the Y in the N number. Unfortunately the plane had a very brief career, as did Mr. Chambers.

P.S. Notice that the size of the N number shown on your scale line drawing isn't correct. Trust the photos.

The tail lettering was changed during the time the racer was at Cleveland. It appears that Chambers had to add bracing wires to the tail assembly and do a quick paint touch-up.

Aircraft of Air Racing's Golden Age Part II by Robert Hirsch and Ross Hirsch. It's a 2 volume slip case set with a lot of information. There are some minor glitches but overall well worth adding to your library. I believe the Hirsch family still has some available.

Cool ship, nice book set, I ordered mine immediately. Thanks Bob.

Jim, typical and legal registration on civil US airplanes up until 1960 or so are small numbers on the tail and big numbers on the top right and bottom left. Once vintage airplanes were starting to become a movement in the country, the law was changed to allow 30 year old airplanes to use the old positioning instead of 12 inch profile numbers. The rules were later changed to allow any airplane 2 inch profile numbers.

Racing planes turned left usually so the racing number was positioned on the bottom of the right wing but not always. In the post war Bendix some years a 6 foot number on the bottom oriented top at leading edge was required so observers could allegedly site the numbers as they progressed past certain city checkpoints. During the 70's Mojave hosted right turning races so some airplanes reversed their number positions from one race to the other. When I raced at Reno I only had 36 inch numbers on the sides of the airplane and none on the wings. I've also helped people change their number colors, fonts and positioning during the event because the contest committee required it owing to timing and scoring not being able to read it.

Photos are the best source and luckily our rules consider both for documentation.

Just about there. I decided I didn't want to do ink lines, every line on the 3-view is represented by a contour on the model.

.

As it sits now, sans tank and controls, 10.3oz.  74 square inches. Should be interesting.
