Stoddard Hamilton

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 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.

In 1981 the EAA awarded Tom Hamilton the prestigious Raspet Award for outstanding contribution to the design of light aircraft.

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 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.

1986 also marked the introduction of the Glasair III, two-place sportplane on the planet. Powered by its 300 h.p. Lycoming IO-540 to cruise speeds in excess of 265 m.p.h., the kit featured all the new labor-saving innovations of the Glasair II kits.

Also in 1986, S-H became an employee-owned company, Arlington, Washington.

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.

SI has manufactured a variety of parts for the 737, 747, 757, 767 and the new 777. SI was one of the first companies in the nation to be approved under the new D1-9000 specification, a manufacturing quality control specification.

S-H introduced the Glasair III Turbo in 1990. A complete firewall-forward package, this option pushed the standard Glasair III airframe up into the Flight Levels at speeds of well over 300 m.p.h.

GlasFloats were developed in 1992. Available in straight and amphibious versions, these all-composite, leak-proof floats opened up new vistas of adventure for builders of light aircraft such as the Kitfox and Avid Flyer.

The Glasair III LP was displayed at the NASA exhibit in Oshkosh in 1993. The result of S-H’s participation in a NASA-funded Small Business Innovation Research (SBIR) grant, the LP was the first lightning-protected composite kit aircraft. Under the terms of the SBIR grant, the research results produced in the course of this project became part of the public domain, and future certified composite aircraft such as the Cirrus and the Kestrel utilize technology based on S-H’s findings. S-H continues to participate in several other SBIR grants and NASA advanced research programs on such topics as composite manufacturing techniques and aircraft crashworthiness.

The Glasair Super II was also introduced in 1993. The II-S fuselage was lengthened by 6″, the wing was moved aft 1-1/2″, and the horizontal tail surfaces were increased in size by 30%, producing an aircraft of peerless handling characteristics with a CG envelope wide enough to accommodate a wide variety of engine and equipment choices. Available in any of three gear configurations, the Super II offers an unbeatable combination of performance, utility and economy.

The new GlaStar was announced at the 1994 Sun n’ Fun airshow in Lakeland, Florida, and first displayed as an almost-finished prototype at Oshkosh. Featuring a foldable high wing, convertible landing gear options and a baggage compartment. More than 100 builders placed deposits on the new kit in advance of the prototype’s November first flight.

The Glasair III Prop Jet also debuted at Oshkosh ‘94. Built by Composite Turbine Tech, Inc., of Toledo, Washington, this aircraft mated a 450 s.h.p. Allison 250 B-17 turbine engine to a standard Glasair III airframe.

Behind its original 125 h.p. Continental IO-240 engine, the GlaStar prototype exceeded its design goals on every parameter in 1995. By the fall of 1995, complete GlaStar kits were being shipped, and the first customer-built GlaStar took flight after less than three-months of construction. 1995 also saw major enhancements to all models of the Glasair.

Kits for both the III and the Super II underwent upgrades, as previously optional equipment was incorporated into the standard kits. Ever-increasing degrees of factory prefabrication, part quality and kit completeness continue to be the hallmark of the Glasair line.

In 1996, the GlaStar prototype, having logged some 400 trouble-free hours in its first eighteen months, was equipped with a new 160 h.p. Lycoming O-320 engine installation. With a constant-speed propeller, this powerplant gave better cruise speed, climb performance and short-field wizardry. In 1997 the GlaStar was tested on floats — both Aerocet 2200 straight floats and Wipline 2100 amphibs. Designed from the outset as a floatplane, the GlaStar exceeded all expectations. In addition, the 180 h.p. Lycoming O-360 engine was installed in the GlaStar.

1997: 18701 58th Ave, N.E. Arlington, WA 98223, USA.

Following a sophisticated computational fluid dynamics analysis of its aerodynamic qualities at speeds in the Mach .6–.7 range, the Glasair III got an enlarged rudder, a new cowling and a mighty turbocharger to become the Glasair Super III in 1998. Designed to produce 350 h.p. at altitudes of up to 37,000 feet, the new powerplant testing on the prototype had been flown to 35,000 feet at airspeeds of greater than 320 knots. At 32,000 feet, the aircraft was still capable of climbing at over 2,000 feet per minute.

GlaStar builders got a tremendous boost in 1998 with the introduction of new “Jump-Start” accelerated-assembly options. Taken together, the Jump-Start Wing and Fuselage options shaved up to 50% off the typical build-time.

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 clo-sure 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 find¬ing the overheads of the line were not self supporting approached Arlington Air¬craft 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.

Mr. Wathen, who sits on the President’s Counsel of the EAA and owns historic Flabob Airport in Riverside, California, selected Mikael Via to be President and Chief Operating Officer (COO) of the new companies. According to Mr. Wathen, Via is to be responsible for daily operations of Glasair Aviation and will help Wathen determine the long-term direction and growth of the company. Via, is a private pilot and builder/owner of a Glasair Super II RG.

More than 3,000 kits were in the field and some 1,700 aircraft flying in countries around the world by 2008.

In 2009 produces kits to construct the very popular Glasair two-seat low-wing monoplane in various models (first flown 1979 and thought to have been the first pre-molded composite kitplane), plus kits for the GlaStar two-seat high-wing cabin monoplane (first flown 1994 and many hundreds sold). Other aircraft have included the Turbine 250/III turboprop two-seater, and T-9 Stalker two-seat turboprop variant of Glasair III as trainer (first flown 1988).

Stits

Ray Stits developed the Stits covering and coatings process, now known as Poly-Fiber. He eventually sold the Poly-Fiber business to Alexander Aeroplane Company, owned by Ron Alexander at the time.

Stits established EAA Chapter One at Flabob Airport in Riverside, California. In 1962, he received the August Raspet Memorial Award and in 1994, he was inducted into the EAA Homebuilders Hall of Fame.

Between 1948 and 1965, he designed and built 15 airplanes. Except for the first two designs, he test flew them all. The reason for not flying the first two relates to the nature of the aircraft: they were the world’s smallest monoplane and then the world’s smallest biplane. Ray was too big/heavy to fit into them.

In May of 1952, he introduced the Stits Sky Baby, a biplane with a 7’2” wingspan. Once again he drew tremendous response from newspapers, magazines and the newsreel companies. And once again he got busy on the airshow circuit…but not for long. After one season, and 25 hours of flying time, the Sky Baby was given to the Smithsonian Institute. In 1963 it was sent to the Experimental Aircraft Association’s museum where it remains on long term loan. Requests were pouring in for plans for both of his midget aircraft, but Ray knew most people couldn’t handle the complexities of construction or the flying limitations of the two designs. Not being one to pass up an opportunity, however, he designed, built and test flew the Stits Playboy. It was a single seat, low wing, strut braced, aerobatic airframe that was designed to fly with 85 hp to 160hp engines.

Capitalizing on his fame for the miniature, Ray began selling plans. Realizing that a lot of builders were having problems securing aircraft grade materials, he started stocking and selling materials. He was into his second decade as an aircraft mechanic when the homebuilt movement began to take off and he slowly transitioned into an early version of Aircraft Spruce & Specialty.

In 1953, Ray got a letter from a man named Poberezny. The letter sat in an office at the airport for six weeks before someone finally delivered it to Ray. Paul Poberezny had heard of Ray’s work with homebuilts and had written to invite him to join a new organization he’d founded called the Experimental Aircraft Association.

Ray liked the concept and suggested to Paul that he be allowed to establish a Chapter of the EAA at Flabob. A couple months later, EAA had amended their bylaws to allow for Chapters and Ray was authorized to set up the first one. He got a dozen friends together and founded Chapter One. It’s still very active and leads all the other chapters in the number of Young Eagles they fly annually.

Around 1961, Ray went out to the back of his shop to dispose of some scrap aircraft covering that had been removed from an airplane. Disposal in those days was done with a match. But when he bent over to torch the nitric dope covered fabric, the stuff blew up in his face. The flammability of the covering got him thinking and he began a course of study that made him a chemist, leading over several years to the creation of a new covering material and a form of paint that was fire-resistant. Stits Polyfiber was born and it became such a hit in the homebuilt and restoration communities that Ray stopped selling all other forms of aircraft materials and by 1969, he removed all of his aircraft plans from the market. He spent the next couple of decades selling fabric and paint of his own creation. Ray retired and Jon Goldenbaum runs Polyfiber, which is still based on the famous “Stits Process”.

Ray Stits went on to become recognized as a Master Mechanic and became one of a handful of people who has also earned the title of Master Pilot. He still flies an LSA and stays involved with events going on at Flabob Airport. His latest gesture was an offer to install a 12,000 gallon fuel tank on the airport’s fuel farm so that Flabob can become the first airport in the state of California to offer mogas to homebuilders and those who own a certificated aircraft with the proper STC. He’s also involved in working with students at the Flabob Airport Preparatory Academy who are rebuilding a Stits Skycoupe.

At the age of 90, he was still going strong as a pilot, mentor, and founding member of EAA Chapter One at historic Flabob Airport. Ray

Stits passed away in 2015.

1919: (Edward) Stinson Airplane Syndicate, Detroit MI.

In 1926 the Stinson Aeroplane Syndicate, West Detroit, Michigan, founded by E. A. Stinson, made Detroiter four passenger biplane designed jointly by Stinson and F. Verville. Name Detroiter was confusingly retained for later monoplanes. Three Detroiter biplanes acquired in 1926 by Northwest Airways Inc, at which time manufacturing company renamed Stinson Airplane Corporation.

1927: Stinson Aircraft Corp, Northville MI.

Detroiters of several forms used widely by commercial and private operators; e.g. flew first regular airmail service in China. Detroiter monoplanes much developed, though general type was claimed as first U.S. aircraft with soundproofed and heated cabin, engine starter and wheel brakes.

Detroiter Junior of 1928 was scaled-down version for private and executive work. Detroiters established several records, including 174 hr airborne, July 1929.

1929: Wayne MI. 1931: Merger with E L Cord Corp.

About 1933 new tapered wing form adopted for Reliant single-engined series, which succeeded Detroiter line. Reliant series was especially successful and built in great quantities, 500 being transferred to Royal Navy under Lend-Lease. Voyager was later two-seat high-wing monoplane. Sentinel liaison type very widely used under Vultee name.
