Building the Wizard - A Competition Hand Launch Glider

By Patrick Dionisio and Marshall Geller

 

Wing assembly weighs 5.22 ouncesThe flapperon hinge lines were cut and routed, the servo pockets dug out, and the channels for the servo wiring were made. Additionally, the leading edge root sections of the wing were prepared with epoxy to reinforce the dowel (to be inserted later), and the two wing sections were glassed together.

 

Flapperon servos and linkage installedThe two VS-100’s with linkages were installed on the underside of the wing and the gap seal glued on to the lower surface. The servo wiring had to be untwisted a bit to provide enough length to reach the RX (located in the nose).

 

Wing retainers and fairing installedThe plywood plate for the rear nylon bolt was epoxied into the fuselage. The hole for the nylon bolt in the rear center of the wing was drilled and tapped, and the fairing installed. The wing was then mounted and squared on the fuselage and the dowel holes were drilled into the leading edge of the wing, through the forward plywood bulkhead. The dowels were then epoxied into place.

 

V-tail assembly and mounting

Since the tails already come pre-cut with the proper angles, they were epoxied together and the joint was glassed for reinforcement. The airframe was then turned upside down and the tail aligned into final position, before being epoxied to the fuse. Glass reinforcement was added at the joint between the tail and fuse.

Battery reconfigurationA 110-mah battery was used in the Wizard to keep weight at a minimum. The pack was modified to allow forward placement in the nose. This meant cutting the shrink wrap and unfolding the square pack on the existing bottom tabs, then re-taping.
