Hummel Aviation, Hummel Bird, Hummel H5 and UltraCruiser all metal ultralight, experimental aircraft

The HummelBird is of all metal construction. Bulkheads are mounted on a simple wood beam, with rivet holes located in flanges of bulkheads, skins are wrapped around and holes drilled back through. Sheet metal is simplest, fastest and most economical way to build an aircraft as Art Rempel has proven with his building a HummelBird and engine in three months building time. Construction is very rugged and is stressed for 6G’s, (5G’s with Witman wing tips).

The complete set of plans contains 26 large (D size) pages with full size templates for bulkheads and wing ribs. A 30 page step by step manual is very complete with all materials listed. Only simple shop tools are required to build the Hummel Bird tri gear or tail dragger. Rigid and shock absorbing gear is shown on the plans. For grass field operation, the shock gear is recommended. Since this is a short build time and quite simple, it is a good project for first for first time builders. Average build time is 1200-1400 hrs if built from scratch. Though a complete kit is not available, al of the welded and many of the complex parts are available.

The 1/2 VW engine has an excellent track record for reliability and fuel economy. Engine plans or complete engines are available.

The FAR Part 103 compliant UltraCruiser

The UltraCruiser was designed as the first all metal ultra light in 1998. First flights were in 2000. First plan sales were in 2001. Intended for first time buiders as well as first time pilots, the UltraCruiser is an easy to build and even easier to fly aircraft.

The design can be built straight from plans up to, and including a full kit. The kit includes predrilled laser cut components. All parts are formed prebent, or welded. Wheels, tires, brakes, harness, and even the seat cushion is included. Wing Spar is pre-assembled. The kit is very complete. Everthing is included to complete the aircraft less the engine, prop, spinner, and instruments.
