Rotorway History

Summary: RotorWay built kit helicopters for amateur builders in Arizona from 1961, renamed RotorWay International in 1990, until its assets were sold to Rotor X in 2021. Its main models were the Scorpion (1967), Exec (1980), Exec 90 (1990), Exec 162F (1994) and A600 Talon (2007).

Origins & 1960s

  • The company was founded in 1961 under the name RotorWay Aircraft by B. J. Schramm in Chandler, Arizona, USA. Wikipedia
  • Schramm initially built a prototype called the “Javelin” using a motorcycle engine (~40 hp) around 1961. Rotorway UK
  • The first production-kit helicopter was the RotorWay Scorpion (1967). It was aimed at the sport-flying public and sold as a kit. Wikipedia
  • The Scorpion was offered for sale in 1967 and is described as the first real personal helicopter on the market that actually flew. News of it generated tremendous excitement in the aviation world. It was an experimental aircraft in the true sense of the word, and a pioneer of individual helicopter ownership. Rotorway UK
  • This was significant: one of the earliest kit-helicopter offerings. The Scorpion evolved through variants. Wikipedia

1970s

  • The Scorpion series expanded. The two-seater version, the Scorpion II (or “Scorpion Too”), appeared around 1971. Wikipedia
  • In 1974 they developed their own four-cycle engine (the RW133) when they couldn’t get a suitable 4-cycle from other manufacturers. The Scorpion 133 used that engine. Wikipedia
  • The 1974 Scorpion II redesign aimed to cut the maintenance time needed for every hour of flight. The first step was to drop the inefficient two-stroke engine. Manufacturing its own engine (the RW133) made RotorWay unique among kit makers, and the company kept building its own engines from then on. Rotorway UK
  • Over the decade, RotorWay built its reputation as a maker of home-built helicopter kits (rather than full certified production helicopters).

1980s

  • In 1980 the company introduced the RotorWay Exec (Executive) and a new engine (RW145). The Exec had a more “finished” look compared to earlier open-frame kits. Wikipedia
  • One of the most significant improvements on the Exec was the elastomeric rotor system, which greatly improved the helicopter’s “workhorse” capabilities. The Exec is the great-grandfather of the Exec 162F. Rotorway UK
  • In 1982 they introduced asymmetrical rotor blades, letting the craft climb higher and making the blades more resistant to erosion. According to Wikipedia, these early blades also carried a greater risk of losing the aircraft if the engine quit. (Rotorway UK later credits the Exec 90’s asymmetrical aerofoil with improved autorotation characteristics. Blades made before and after 9/90 are treated differently in the service bulletins.) Wikipedia
  • In the late 1980s RotorWay created the Elete, a larger two-place helicopter powered by the RotorWay 152, a water-cooled, dual-ignition four-stroke engine. Only three Eletes were sold before the company was bought by a former customer, John Netherwood. Rotorway UK
  • The company faced serious financial difficulties in the late 1980s and went out of business. Its assets were bought in 1990 (see below), as AOPA Pilot’s 1995 “Kit Copter” article recounts. AOPA

1990s: Re-organization & New Ownership

  • In 1990, RotorWay Aircraft underwent re-organization and changed its name to RotorWay International. Helis.com
  • That year, British businessman John Netherwood (who had been a customer) purchased the assets of the failing company, rehired many workers, and restarted operations under the new name. AOPA
  • Under the new owner the Exec was reviewed from top to bottom. Almost every aspect was improved, including how the kit was packed and organised, the manuals, and the customer service programme that gave builders technical support. The result was the Exec 90. According to Rotorway UK, it was the only piston-powered helicopter of its time to use an asymmetrical aerofoil, for better autorotation characteristics and safety. Rotorway UK
  • He introduced the Exec 90 and later the Exec 162F (mid-1990s) which featured more modern components: fuel injection, FADEC (full authority digital engine control), improved rotor blades and kit support. Rotorway UK
  • The Exec 162F (1994) replaced the Exec 90’s carburetted engine with fuel injection, electronic ignition and redundant (dual) FADECs. FADEC was unheard of in the experimental category at the time and used by only a few certified helicopter makers. Over the following decade the 162F became the number-one choice in the personal-helicopter market. Rotorway UK
  • The company moved into a new factory in Chandler (~1994) and improved its assembly/kit process. Rotorway UK

2000s & Later Developments

  • In July 2007, RotorWay launched the RotorWay A600 Talon, a further improved two-seat kit helicopter, intended to modernize their lineup. Wikipedia
  • The A600 Talon is the eighth-generation RotorWay and the successor of the Exec 162F. Its upgrades include a shaft-driven tail rotor, higher and wider landing gear, an electric clutch, a cog-belt final drive and a glass cockpit. Rotorway UK
  • In February 2009, RotorWay acquired PMC Machining & Manufacturing to bolster its manufacturing capability and to move toward certifying a two-seat turbine helicopter (with the Rolls-Royce RR300 engine). AOPA
  • A later development is the A600 Talon Turbo, with a turbocharged engine giving more power. Rotorway UK reports that pilots who have flown it call it a “game changer”. Rotorway UK
  • The company claimed to be the oldest and largest kit-helicopter company in the world, with kits sold in over 50 countries. Rotorway UK

Ownership Changes & Fate

  • In 2007 the upper-level management/investor group (Grant Norwitz, Bill Adams, Judy Craven) acquired RotorWay. Flightmann
  • Rotorway UK states that the company later became Chinese-owned, while the factory stayed in the USA (date not given). Rotorway UK
  • In 2021, the company’s plant, designs and assets were purchased by a new company, Rotor X Aircraft Manufacturing Co., and RotorWay ceased business as such. AOPA
  • Rotor X filed for Chapter 11 bankruptcy protection in October 2023. The case was dismissed later that month and closed in November 2023. Wikipedia

Significance & Legacy

  • RotorWay pioneered the “kit helicopter” market: giving amateur builders the ability to assemble their own helicopters. Aviation Week
  • They manufactured many of their own critical components (engines, rotor systems) rather than sourcing everything externally — notable for a kit-manufacturer. RotorWay Canada
  • Their technology improvements (FADEC, asymmetrical rotor blades, etc) show a movement toward more advanced amateur-builder helicopters.
  • While they never achieved full certification (commercial production) of large numbers of helicopters, their presence in the home-built rotorcraft field was substantial.
