Foo Fighter Biplane 

We are sorry but Don is not longer selling Foo Fighter plans.   You might try a wanted ad on barnstormers.com

The Foo Fighter was designed and built in 1967 by Don Stewart and Tom Raybourn,  both Mohawk Airline pilots, and inspired by the Alcock A-1, a World War I war bird that resembles the Sopwith Pup. .

  Don says- "I first flew the Foo Fighter with the Ford Falcon 6 cylinder engine with geared prop speed reducer. It weighed too much and didn't develop nearly the HP claimed.  I later changed the powerplant to a Franklin Sport 4 - 130 hp."

The Franklin Sport 4 engine went out of production and so the airplane was once again redesigned to accept any of the four cylinder Lycoming engines from the O235 up to the O320 series. One distinguishing feature of the Foo Fighter is its lower wing that crosses below the fuselage, aft of the gear, and attaches on the centerline. The airframe is built from steel tubing and covered with fabric. It is a very docile sport airplane that offers limited aerobatic capabilities.

Don says-  That's Carl Pflanzer in the cockpit and me propping it.

Don says, " this photo below is my good friend Carl Pflanzer in the airplane at OSH in the early 70s. Tom Rabourn, Carl and I brought it there and put about 20 hours on it during the fly in. I bought the Franklin Sport Four engine kit for  1200 bucks!

So far as I know there are three built now. The original is in California. (Don wishes he still had it.)

One of the nicest flying airplanes I ever had my hands on."
