Wells 1910 Glider
An aerodynamic design built by Daniel D. Wells of Jacksonville, Florida, during 1909/1910. Wells, an early inventor, patented the skid (US Patent 935075) and claimed to have made models with wing-warping already in 1897.
An aerodynamic design, designed and jointly built by a local mechanic, Daniel D. Wells, and a 21 year old machinist of the Seaboard Airline Railroad, Robert Kloeppel, who had just come to Jacksonville from Germany a few years earlier.
Unable to afford an aircraft engine at the time, they installed a Franklin automobile engine.
Kloeppel had received no flying instructions except those he read in a mechanics magazine, yet he shortly prepared the flimsy craft for takeoff. Flexing his piano wire controls he applied power and the plane moved rapidly about 75 feet and rose briefly four or five feet in the air, but when he sought to gain altitude by applying full power, the crankshaft suddenly broke and the plane settled down to earth, a complete wreck. Kloeppel was uninjured but never again built another plane or attempted to fly one.
Weller-Lusk Model 1
In 1930 R C Lusk & R M Weller partially built the Model 1 monoplane with a 100hp Kinner engine. Apparently it was not completed but registration was applied for and issued as N334V c/n EX-1, but cancelled on 4 March 1930.
Weller UW-9 Sprint
In production in 2012, the Weller UW-9 Sprint is a German ultralight aircraft designed and produced by Weller Flugzeugbau of Bibersfeld.
The UW-9 is intended as a nostalgic 1930s style design that would comply with the Fédération Aéronautique Internationale microlight rules. It features a strut-braced parasol wing, a two-seats-in-tandem open cockpit, fixed conventional landing gear and a single engine in tractor configuration.
The aircraft fuselage is made from welded steel tubing, with bolted-together aluminum tubing spar ladder-construction wings, all covered in doped aircraft fabric. Its wing has a cut-out in the centre trailing edge for rear cockpit access. The wing is supported by “V”-struts and jury struts. The tailplane is also supported by “V”-struts.
Standard engines available are the 70 hp (52 kW) Sauer UL 2100, the 75 hp (56 kW) Limbach L2000EA, the 100 hp (75 kW) Rotax 912ULS four-stroke powerplants, or the 85 hp (63 kW) Rotec R2800 radial engine. The Sprint is approved for aero-towing gliders and banner towing in Germany.

Weiss Olive
While working for Pemberton Billing, Eric Gordon England met José Weiss, who designed and built tailless gliders, and England became an assistant to Weiss. On 27 June 1909, Gordon England flew a Weiss glider (named Olive after one of Weiss’s five daughters), at Amberley Mount, Sussex, on a height-gaining flight that reached 100 feet. It is the first recorded soaring flight, and is considered to be the birth of the sport of Gliding.

Weir Draggin Fly
Draggin Fly was designed to be easy to build, inexpensive to fly and maintain, strong, safe, easy to fly with a stock 1600cc VW engine. Ron Weir recommends using only the 1600cc or 1700cc VW — “Smaller engine won’t fly it well, and a larger engine won‘t balance the plane well.”
