Azza and Sonny are well known for their close formation aerobatics and this was another brilliant flying slot at the Cosford Large Model Association Show featuring their two Bill Hempel Clipped Wing Cubs. These radio controlled aircraft have a wing span of 18 feet (216 inches) and are designed for the 3W-275cc engine but Azza and Sonny used the ZDZ 420B4-J. The weight is approximately 94-96 pounds.

Wow!!   

Beautiful models, and fantastic formation flying. And I loved the wing-waggle on the final pass!
