(made in 1985)

The Magic 4 is set to become a classic 5th generation glider. It is based on a Magic 3 sail but features a complete review of the airframe in order to reduce drag to a minimum. The kingpost has a deeper airfoil section offering lower drag coefficient, while wire junctions are tucked into a neat new top to give a clean finish. The crosstubes are lighter, being larger diameter than before, with a new wing bolt connection. The uprights are now of deeper section fore and aft with a larger diameter internal tube. Injection mouldings are used extensively to give a high standard of finish. The nose catch has been moved back along the keel slightly to allow the fitment of the now standard nose cone. In order to give easier pre-flight inspection of the wing bolt connections two zip pockets have been fitted. The ball tips have been lightened and combined with the new crosstubes a reduced roll yaw inertia has been obtained.
