About this Plan

Comet Racer. Rubber sport model.

Quote: "The Comet Racer. By Don Orman The winner of the senior gas model event at the Junior Aviators National Meet designed and flew this racer 91.4 mph at a club contest.

THIS model was designed and built for a club contest in Akron. Models of this design have been clocked at 91.4 miles per hour over a 120-foot course. A second model with slight modifications turned in a speed of 96 mph. It averaged 80 mph for seven flights over the course. Construction is remarkably simple, and should register well with beginners for this reason. Yet the high speeds it attained make it worthwhile for the more experienced.

Two types of construction have been used in the wing and tail surfaces, solid and built up. The model with the solid balsa construction turned in a slightly higher speed. While the plans have been prepared for the built-up wing and tail construction, either type is readily used. The necessary materials have been listed for both types.

The fuselage is built of 1/16in square hard balsa. First lay out the two side panels - one over the other. Cut the bracing and cement in position. Note that the top and bottom outline of the fuselage is a straight line in the side view from about a third back. Auxiliary 1/16in square braces are cemented in the nose of the model, running alongside the longerons from the fourth cross-brace forward..."

Quote: "Attached... plan for the Comet Racer by Don Orman, published in the August, 1938 edition of Air Trails. I checked, but could not find a current plan on Outerzone. There is a supplementary file of the magazine build article. Wingspan 9 inches. The designer flew it at a reported 91.4 mph. PB_guy"

* Credit field

The Credit field in the Outerzone database is designed to recognise and credit the hard work done in scanning and digitally cleaning these vintage and old timer model aircraft plans to get them into a usable format. Currently, it is also used to credit people simply for uploading the plan to a forum on the internet. Which is not quite the same thing. This will change soon. Probably.


This model plan (like all plans on Outerzone) is supposedly scaled correctly and supposedly will print out nicely at the right size. But that doesn't always happen. If you are about to start building a model plane using this free plan, you are strongly advised to check the scaling very, very carefully before cutting any balsa wood.
