In September 2009 the plans were available and cost US$350.00. The welded parts, bulkheads, ribs and misc. other parts were available for scratch builders and kits were being developed. The H5 is basically a slightly modified Ultracruiser Plus. The major difference is the style of the canopy, turtle deck and dorsal fin area. It is now like the Hummelbird. We also wanted to get away from the name Ultracruiser Plus because of the confusion it caused since we had a plane called the Ultracruiser. People thought the Plus was an Ultracruiser with some option added as opposed to a completely different airplane.
Optional wing tanks allow 21 USgallons of fuel.

Hummel Bird began as a modified Watson Windwagon, but the designer/builder, Morry Hummel, of Bryan, Ohio, highly modified it and called it Hummel Bird, using the Revmaster R-800 rather than the half-VW. The LSA airframe has been modified and strengthened, tail area increased, and a locking tailwheel added for better ground control. A high L/D Schreder #3 airfoil and flaps also were used.

Excellent single place aircraft. Features all aluminum construction. Fast and inexpensive to build, many were flying.
