Stoddard Hamilton SH-2 Glasair

Glasair RG

Designed in 1976 and first built in 1979, the Glasair is an all-composite, side-by-side two-place airplane which makes use of female molds to fabricate kit parts. The Glasair is con¬structed from preformed composite shells provided by Stoddard Hamilton Aircraft. Such a technique offers structural integrity without use of steel tubes or aluminum. A one-piece wing was designed to take advantage of skin strength without joints. A one-piece spar is made in a mold at the factory out of unidirectional glass for spar caps and bidirectional glass on a 45-degree bias for the shear webs. This is then bonded into the lower wing shell to save amateur builders time. The fuselage is built from three main pieces and requires no jigging but only three bulkheads, the firewall, seatback and a small aft bulkhead. The landing gear legs are pressure-molded unidirectional glass. A 160-hp version can also be built.

Tom Hamilton began flight testing the Glasair TD in 1979. Originally powered by a 115 h.p. Lycoming O-235 powerplant, the TD prototype featured conventional landing gear and a gross weight of 1,600 lbs.

Glasair TD

Glasair debuted at the EAA Convention in Oshkosh 1980 with the first premolded composite kit aircraft ever offered. All the major airframe components pieces such as the fuselage, wing, cowling, and tail feathers were already fabricated in two halves. All the builder needed to do was install the ribs or bulkheads and seam the halves together. All the parts came direct from the factory with a mirror-smooth gel coated finish. Thus, the Glasair kit offered tremendous time savings compared to the scratch-built projects that were then available.

In addition, the production kits featured a 3″ higher canopy for improved cockpit comfort and visibility, as well as the more powerful 160 h.p. Lycoming O-320 engine. 150 builders in 1980 alone ordered the Glasair as their kitplane. The Glasair, powered by a Lycoming 0-320, returned a cruise speed of 221 mph at 75 per cent power. Winning the EAA’s prestigious “Outstanding Aircraft Design” Award in 1981, it was only a short time before Stoddard-Hamilton captured a large share of the GRP kitset market.

Units delivered to June 1981: 78. Price 1982: $8,600 (Excludes engine).

The retractable tricycle gear Glasair RG was introduced in 1983, and at the same time, kit completeness for both the RG and the TD was greatly improved. The introduction of prefabricated rudder pedal assemblies, aileron and elevator bellcranks, control stick yokes and various other metal parts completely eliminated the need for welding or complex metalworking skills on the part of the Glasair builder. The retractable undercarriage version has a 1.5 square foot frontal area and 234 mph cruise on 160 hp.

Apart from the undercarriage, the TD and RG models are otherwise fairly identical, the latter naturally featuring the higher performance.

Glasair RG

John Murphy of Cocoa, Florida, showed up at Oshkosh 1983 with a fixed tri-gear Glasair. Although Stoddard-Hamilton offered a fixed gear conventional and a retractable tricycle, they did not offer a fixed tri-gear version. Stoddard-Hamilton were impressed and planned to add the option to their line.

In 1984, working from a new 80,000 square foot factory, the company produces 3 Glasair kits a week. More than 600 kits had already been sold.

The fixed tricycle gear Glasair FT was developed in 1984. Making the new landing gear retrofittable to existing TDs, S-H converted the original production prototype, N89SH, to the new gear configuration. The new FT gave up only 2 m.p.h. of speed to the tail dragger.

With some 700 Glasair kits in the field in 1986, enter the Glasair II, which was simultaneously introduced in TD, FT and RG models. The main areas of improvement over the original Glasair I centered on cockpit ergonomics and labor savings. A complete retooling of most of the composite parts resulted in an additional 3″ of cabin width and 1-1/2″ of cabin height.

These changes also resulted in a larger baggage compartment. S-H’s labor-saving campaign resulted in, among other things, premolded mounting joggles for such components as the wingtip fairings, cowling, and so on; factory-made cutouts for the canopies and windshield; and premolded scribe lines in parts that required builder cutting. The end result was a more comfortable, more practical, better engineered aircraft that was more enjoyable to build as well as to fly.

In 1989 the Glasair II-S models were introduced — ‘S’ for stretched. The original II fuselage was lengthened by 14″, providing easier installation of the more powerful 180 and 200 h.p. engines builders were installing, as well as improving the appearance of the aircraft.

As before, tail dragger, fixed tricycle and retractable tricycle gear were all offered on the II-S. 1989 also marked the founding of Stoddard International, Inc., a sister company organized to produce composite parts for the Boeing Company.

Original manufacturer of the Glasair and Glastar, Stoddard Hamilton closed its doors in 2000 after more than 20 years in business. Both aircraft types were split from the Stoddard Hamilton camp when the closure occurred.

Thomas W. Wathen, former Chairman and CEO of Pinkerton’s, Inc., purchased the assets of Stoddard-Hamilton and AADI and formed Glasair Aviation, LLC in 2001 for the continued manufacturing and sale of both the Glasair and Glastar product lines.

New owner Thomas Walthem was committed to getting all three kits back into production. He initially purchased the Glasair side of the business but after finding the overheads of the line were not self supporting approached Arlington Aircraft Development Inc (AADI) to purchase the GlaStar line. As a single entity, the Glasair and Glastar kit aircraft under the banner of New Glasair/GlaStar.

In 2009 produces kits to construct the very popular Glasair in various models.

Stockhausen 1912-1913 biplane

In 1910-1911, a small group of aviation enthusiasts from Paderborn, Johann Stockhausen, Oskar Martini, Paul Schröder, Karl Vogt and Anton Bickmeier built their tents on the edge of the parade ground at Dörenkamp in Paderborn, Germany, working on their projects for the conquest of the air, but nothing further is known.

In February and March 1911, Stockhausen and Schröder leased on the edge of today’s airfield Bad Lippspringe, the former parade ground, a land on which they built the first Paderborn aircraft hall proudly bearing the name “Aeroplanhalle Joh. Stockhausen”. For the 17 May 1912 Stockhausen invited pilot Gustav Tweer. The biplane of Stockhausen had a 60 hp engine.

In 1955 Ray Stits designed the Flut-R-Bug, his sixth design. It was originally a single-place, mid-wing, nosewheel airplane and several variants followed.

The first Flut-R-Bug was the Model SA-5A, followed by the SA-5B. Stits also designed tandem versions (SA-6A and SA-6B) and then the two-place, side-by-side SA-6C. The Flut-R-Bug was typically powered by either a small Continental or Lycoming engine.

Stits SA-4A Executive / Stits-Besler Executive

SA4A Stits Besler Executive Courtesy Don Stits

The 4th design of Ray Stits, the Stits-Besler Executive project was initiated when William Besler of Besler Corp. contracted Ray Stits to design a three-place homebuilt aircraft with folding wings. Besler was an early aviation experimenter, who had mounted a steam engine of his own design on a Travel Air 2000 in 1933.

Ray Stits designed the three place Stits SA-4A Executive, developed from the Stits Playboy. Only one was built, costing $6000 in 1955.

The wings on the Executive fold aft and upward. Fuel tanks are embedded in the non-folding wing roots. The fuselage is welded steel tube with fabric covering. The ailerons are mounted in the center of the wing rather than the tips.

The sole Executive, (registration no. N36K), has been used as a test bed for Besler-designed engines; a 150 hp (112 kW) steam engine and a two cycle, four cylinder Vee rated at 100 hp (75 kW).

The Stits SA-7 Skycoupe was one of the most common homebuilts in the early 1960s. It could be built for around $3,000 back then.

SA7B Skycoupe Courtesy Don Stits

The SA-7 Sky-Coupe was Stits’ initial entry in the “ready-made” two-place aircraft market. About 1956, the SA-7A N5581V was powered by a 65hp Continental engine.

The 1957 SA-7B N5594V had a re-designed fuselage and tail; elevator trim tab and was powered by a 65hp (later 85hp) Continental engine.

One custom-built fuselage only SA-7C was built for a 125hp Lycoming engine.

SA-7D

The SA-7D Skycoupe, very similar in appearance to a Piper Colt, is of typical construction for aircraft of the late 1950s — welded chromoly steel tube fuselage, wooden wing, fabric covering, powered by a 125-hp Lycoming O-290-D converted from a military ground power unit.

About 1961 the SA-7D designed by Harold Dale and Ray Stits was a production version supplied in kit and blueprint form. Power options were up to 100hp.

The design proved so popular that Ray Stits, the designer, and his business partners took it through certification.

The Type Certificate for the Stits Model SA-9A Skycoupe was granted by the FAA in December 1961 after four years of testing.

Stits SA-8A Skeeto

SA8A Skeeto Courtesy Don Stits

The Stits SA-8A Skeeto is an early homebuilt ultralight design by Ray Stits initially intended to be an affordable light aircraft that could be built complete for under $500 in 1957. The fuselage was welded steel tubing, with mostly fabric covered wood construction for the wings and control surfaces. The engine for this kit venture was to be an off-the shelf low cost model.

Test model 1 was a 4 hp (3 kW) Continental modified for 6 hp (4 kW).
Test model 2 was a two cycle 3.5 hp (2.6 kW) engine with a belt reduction.
Test model 3 used two engines on a single v-belt making it a 4 hp (3 kW) twin engine which flew at 25 mph.
Test model 4 had a homelite chainsaw engine at 7.5 hp (5.6 kW)
Test model 5 used a Disston chain saw engine at 9 hp (7 kW)
Test model 6 used a Disston chain saw engine mounted inverted.
Test model 7 used an Inverted Evinrude 25 hp (19 kW) outboard boat motor.
Test model 8 used a right-side up Evinrude.

SA-8A Skeeto c/n 301

Test flights were limited to the length of the runway after the aircraft was registered as a “research and development” project. The roll rate was so low at 20-30 mph, that rudder turns were preferred. The 3-4 pound wing loading was considered impractically light for handling. An example of a SA-8 Skeeto was donated to the Claremont, California Air Museum in 1958, it is now in the EAA AirVenture Museum in Oshkosh, Wisconsin.

Stits SA-11A Playmate

Designed by Ray Stits, the SA-11A is a single engine, side-by-side configuration seating, tricycle gear, strut-braced, low wing monoplane. The fuselage is welded steel tubing with aircraft fabric covering. The wings have a quick release mechanism that allows them to fold and lock alongside the fuselage in 15–30 seconds. Safety mechanisms were put in place so pilots could visually inspect that the wings were locked in place. A small sideways seat in the rear can accommodate 150 lb (68 kg) of luggage or a light passenger.

The prototype was donated by Ray Stits in 1969 to the EAA AirVenture Museum in Oshkosh, Wisconsin. Its engine went into the Stits SA-9A “Skycoupe” prototype for testing and development.

Stits DS-1 Baby Bird

In 1980, Don Stits began the design the Baby Bird, a tiny high-wing monoplane, with the goal of setting a new “Worlds Smallest Airplane” record. With the help of his wife, Lori, and their two children Ray and Jennifer, construction began in the family garage.

The Baby Bird’s fuselage and tail were constructed of steel tubing, the 6 ft 3 inch wing of spruce, and completed with fabric covering. Baby Bird was powered by a 55hp Hirth engine swinging a ground-adjustable wood prop.

By the summer of 1984, the Baby Bird was ready for taxi tests. Don’s friend, Harold Nemer, was chosen to pilot the Baby Bird based on his experience and size. In August 1984, Baby Bird completed taxi test and made its first flight. Over the course of time, Nemer completed 35 flights before Don retired the Baby Bird having reached his goal of resetting the record with a monoplane.

In 1986, the Baby Bird was registered in the Guinness Book of World Records as the “Smallest Monoplane in the World”.

Don donated the Baby Bird to the EAA AirVenture Museum in 1989.
