Cozy Mk IV+

What is the Cozy Mk IV?

The Cozy Mk IV is a custom built canard pusher aircraft built from composite material. Usually called Experimental, the Swiss designation is an amateur built aircraft. Here in Switzerland the RSA Suisse is supporting us with help, tips and tricks, engineering and last but not least the interface to the BAZL, the Swiss FAA.

Mark Beduhn's Cozy Mark IV, N494CZ

This is a flying example, N494CZ, built and flown by Mark Beduhn. Recently his plane has been used by the CAFE foundation for a series of flight tests:

Mark: "They are still analyzing the data, so I don't have the results yet, but they will be published in Sport Aviation in a couple of months. Overall the experience was fantastic! I met some very dedicated, talented and professional aviation enthusiasts who were a pleasure to work with. I feel very fortunate to have had to opportunity to get my plane analyzed in such detail. C.J. Stephens (the test pilot) did share some comments with me. Overall he liked the plane and said that it performed very closely to the numbers published in the owner's manual. He said that matching the numbers in the manual is very unusual, and is a real credit to the designer (Nat Puffer). He (the test pilot) built and owned a vari-ez, and he said my plane flew very much like his except mine has more power and is harder to slow down for landing (probably due to its increased mass)."
