RC / Scale Models of the STOL CH 701

A number of scale model and radio control (r/c) aircraft builders and enthusiasts have constructed plans-built models of the STOL CH 701 and 801 designs from Chris Heintz.  The aircraft presents some unique and very effective short take-off and landing features used on few designs.

	This full-size STOL CH 701 visited a 250-foot R/C model plane field in Reedsburg, WI. The R/C club newsletter stated that the R/C models "use more runway than he did for takeoff!"
	Robin Fowler's STOL CH 701 model: "The model is a traditional balsa interpretation of the CH 701 at 25% scale and is based upon an example kept at Great Oakley UK. (The owner is not the pilot in the model - she is a figment of my imagination!)  It uses Futaba 6EX 2.4ghz radio with mechanical mixing for the flap and aileron functions."

	A hand-made flying model built by an actual STOL CH 701 builder:  "It's a not-to scale non-flying paper model. To make one requires a few cold beers, a good cardboard piece, a sheet of art paper calendar and a small tube of glue. A bad CD works well for twirling propellers with epoxy clay on a pencil for spinner and shaft."

George N. of Lakeland, Florida sent these photos of his handmade STOL CH 801 model:

I ordered a box of various sized balsa sheets and sticks and got started thinking about construction ethods for such a unique aircraft. I probably spent more hour thinking about it than building it! Finally, on December 13th, I made my first test flight. I am pleased to say that it was successful, and I now have completed 7 flights with success. The airplane is semi-scale at 1/5th scale (73" wingspan), as I chose to make the fuselage 6" wide rather than 8", and the cowling is less than scale, but I am very pleased with it's overall looks and performance. It certainly catches the attention of all my fellow club members, who are amazed by its unique features. I am an old Army Aviator (rotary wing) and also hold commercial license for helicopters and fixed wing aircraft, but I have not been active in flying for some time. I hope to see your airplanes again at next Sun n Fun and study them in more detail. Thanks for a great design!

Mark F. sent us these photos of his STOL CH 801 with a 20-inch wing span; built of balsa and tissue; powered by rubber. First flight was April 8, 2001.

(Send us photos of your scale model should you decide to build a STOL CH 701 / 801).
