I love the undercarriage deign. 

I like that they were so optimistic about it that they installed retractable gear.

The Arnold AR-5 is an experimental single seat, low-wing sport monoplane with fixed conventional undercarriage, designed and built by Mike Arnold.

 

Originally conceived by Mike Arnold as a personal sport airplane with excellent performance and good handling qualities. The design outperformed initial performance estimates for its relatively low power output, exceeding 200mph with only 65hp. Constructed of fiberglass-epoxy matrix composite material utilizing the "moldless method" popularized by Burt Rutan. Careful attention to aerodynamic detail resulted in noteworthy laminar flow drag reduction, as documented by aerodynamicists Alex Strojnik and Bruce Carmichael.

 

In 1992, the AR-5 flown by Mike Arnold set the FAI C1a Class World Speed Record of 343,08 km/h over a 3.0km course Mike wrote several articles about his design methodology for various magazines. The sole existing example resides at the Hiller Aviation Museum, San Carlos, CA.

The Ganzavia GAK-22 Dino was an unusual light utility aircraft built in Hungary in the early 1990s. In configuration, it was a biplane with cantilever wings and a very pronounced negative stagger, making it almost a tandem wing design. The pilot and a single passenger sat side by side under an expansive bubble canopy, and it had a fixed tricycle undercarriage. The fuselage was of welded steel tube construction, and the wings of duralumin, with the whole aircraft skinned in fabric, other than the forward fuselage which had aluminium skin. A single prototype flew in 1993, but the project was abandoned by the mid-1990s, with the aircraft itself placed in the Transport Museum of Budapest (Közlekedési Múzeum).
