The Haufe HA-S-2 Hobby is an American, high-wing, single seat glider that was designed by Bruno Haufe and Klaus Hill for amateur building and first flown in 1967.[1][2][3]
Design and development
The HA-S-2 all-metal sailplane design was built as a follow-on to the previous Haufe-Hill collaboration, the Haufe HA-G-1 Buggie all-metal utility glider. The HA-S-2 took five years to design and build and first flew in Utah in 1967. The aircraft features a fixed monowheel landing gear, spoilers and is registered as an Experimental - amateur-built.[1][2][3]
After the prototype HA-S-2 was finished a second example was completed from plans by Russell Worrell of Morgan, Utah in 1971. This version has a cockpit that is 2 in (5.1 cm) wider and has in increased wingspan of 43 ft (13.1 m), 1.8 ft (0.5 m) greater than the original. The second example was designated as the HA-S-3 Hobby and is also registered as an Experimental - amateur-built.[1][2][4]
