This Profile scale model of an Aeronca 7Ac Champ was built from plans by R. D. Hawes in the Flying Aces Club Newsletter (Jan/Feb 2009 No. 245). It is light, with an airframe weight of 11 grams and rubber motor weight of 1.4 grams. The motor is an 8.5 inch loop of 1/8 inch wide FAI Tan rubber, about the length from the propeller hook to the rear hook. I tried narrower and longer motors, but did not get climb. The propeller is a 6 inch diameter one from North Pacific, lightened by sanding. Winding to 750 turns, I've gotten 50 second flights in Memorial Hall. It is a docile flyer, with cubic wing loading just above 2 ounces per cubic foot.

This model of the Dayton-Wright Racer is built with a profile fuselage covered on one side. Wing span is 16 inches Information on the prototype is available at Dayton-Wright Racer - Wikipedia and is displayed at the Henry Ford Museum in Dearborn MI. It had a variable camber wing and retractable landing gear, both remarkable for the early 1920's. I've flown my model in an old Hangar in Rantoul, IL, and one flight lasted 80 seconds. A kit is available from RetroRC, and plans by Mike Welshans are in FAC newsletter issue 258 (March/April 2011).

The Dornier Falke was a prototype 1922 fighter plane made in Switzerland, but designed by the German Firm Dornier, getting around the Versailles Treaty's bans on German arms. It was also evaluated by U.S. Navy as Wright WP-1 after Wright corporation imported one. See http://en.wikipedia.org/wiki/Dornier_Do_H for data on the full scale airplane. This No-Cal plane is about 1:18 scale, and has a Profile fuselage with covering on one side. I built it from plans published by Dave Linstrum in Model Aviation, the AMA magazine in 2008. I have flown it indoors, but some clubs have outdoor contests for these light craft. Silver tissue is Esaki grey tissue spray painted with Krylon silver, as Linstrum suggested.
