Welch Aircraft Industries OW-1
The first original design by Orin Welch was the 1927 OW-1 open cockpit biplane. Four were built; N817 c/n 103, N4205 c/n 100, N5105 c/n 101, and N6838 c/n 104.
The first OW-2 was a modified OW-1.

Welch Aircraft Industries 1927 biplane
Designed by Fred Parker and Orin Welch, the open cockpit 1927 biplane was loosely based on a Swallow design. One was built, N1405, with. “Elephant ear” ailerons, and faired-in radiator underneath. The first production for Welch Co, dubbed Miss Anderso, it was used as a company hack until its eventual sale. Badly damaged after a forced landing in a cornfield, it went into storage, then lost.
Engine: Curtiss OX-5, 90hp
Wingspan: 36’0″
Length: 28’0″
Useful load: 800 lb

Wells Biplane
In 1915 model airplane builder Harry Wells built a full-size single place open cockpit biplane patterned after Laird’s Baby Biplane
Powered by a 12hp 2-cyl Kemp engine, Wells was often seen taxiing around the field, but never flying.
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.
Wells Aviation Reo
In 1915 designed and built the Reo, a small single-seat biplane. Went into liquidation 1917, but production continued under Sir Samuel Waring.
Wellington Sport Mk 1 Pup
The 1966 Sport Mk 1 Pup two place open cockpit biplane was originally powered by a 160hp Kinner R-540, and later a 220hp Continental W-670.
Only the one was built, registered N2312C.
Wingspan: 26’0″
Length: 19’9″
Useful load: 630 lb
Max speed: 118 mph
Cruise speed: 103 mph
Stall: 50 mph
Range: 350 mi
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.

The aircraft is supplied as a kit for amateur construction or as a complete ready-to-fly-aircraft. The 2011 unit cost was €55,000.
