The JayBird Rx2T is a fast, high performance, two-place, aerobatic sport airplane. As with all airplanes designed by McMullan Aircraft Design, the airplane is designed for big, tall pilots. Pilots and passengers up to 6' 4" tall and baggage fit comfortably into the 45 inch wide cockpit. The airplane will accommodate engines from 150 to 230 horsepower but was designed exclusively for the time tested and proven Ford 3.8 liter V-6. The Douglas Fir and Birch plywood fuselage offers great safety and strength to the airframe. The JayBird Rx2T uses the same fuselage and engine as the JayBird Rx2 but uses a tapered wing and taildragger landing configuration for faster cruise speed and better climb performance.

Construction Materials

‚ Wood is still one of the best materials for building an airplane. It is easy to work with and only needs inexpensive tools to work with. For this reason the JayBird is built with clear vertical grain Douglas Fir and Birch aircraft grade plywood.
