AirfoilZ Edge 540 FullFuse 40" wingspan aerobatic airplane kit. AirfoilZ designs and produces model aircraft that are FUN to fly with a best in class performance! Following the path blazed by their YAK and Edge, the AirfoilZ Edge 540 can fly in 15-20+ MPH winds, and excels in both 3-D and IMAC style flying. The fuselage uses a hybrid construction consisting of a foam skin with a lite-ply crutch assembly. This construction results in a lightweight, extremely RIGID, no twist design. The wing uses their proven folded Depron skin, balsa I-beam spar design. The plane comes as a kit with laser cut parts that are designed to interlock together for proper alignment. The fuselage usually takes less than 1 1/2 hours to assemble. The plane uses two servos for the ailerons and one each for the elevator and rudder. New for the Edge 540 is a pull-pull rudder set-up. The Edge 540 kit comes complete with hardware and decals.
