YJTB4 RotorWay Exec 162F c/n 5128 - "Christina Onassis" - Entrepothaven in Rotterdam, Holland - 16 December 2016 more amateur built helicopters

The RotorWay Exec 162F is a two-seat, skid-equipped, two-bladed helicopter, manufactured by RotorWay International of Chandler, Arizona, USA, and supplied in kit form for amateur-construction. The RotorWay Exec 162F kit is one of the most complete kits you can buy; everything is included in the kit except for radio and paint. All small parts are shrink wrapped on cards and included in the first part of the kit are the build manuals, plans and 8 full length videos that take you through the build.  Many of the larger parts are built up at Rotorways Arizona factory; this includes the tail boom, the main shaft and swash plate assembly and the engine which has been test run. The 150 hp engine its self has many safety features including dual ignition, dual fuel injectors and a FADEC engine monitoring system. The main airframe is made of 4130 Chrome Moly steel and no further welding is required through out the entire kit. After arrival of the kit in eight large crates, it takes roughly 800 to 900 hours to complete the helicopter. The RotorWay Exec model was introduced first in 1980. In August 1994, the Exec 162F was introduced and replaced the Exec 90 of the 1990s. The big difference of the Exec 162F with respect to the Exec 90 is the FADEC (Fully Automated Digital Electronic Control) of the fuel injection system of the engine. The Exec series was further developed into the RotorWay A600 Talon, which replaced the Exec in production and production of the RotorWay Exec 162F came to an end in 2011. Rotorway kits, which lack only avionics and paint, are marketed in USA and 50 other countries; 40% of production is shipped abroad. About 2,500 of the various RotorWay models have flown, although only about 60 percent are in flying condition at any one time.

In 1958, B.J.Schramm set up the Schramm Aircraft Company to develop and market his Schramm Javelin, a single-seat amateur-built helicopter, which testing begun in 1961. Schramm subsequently redesigned the Javelin as the Schramm Scorpion, whose prototype was first flown in 1966. To market and produce kits for this revised version he formed Rotorway Aircraft Inc. In 1967, RotorWay Aircraft Inc. started production of its first kit helicopter model: the single-seat RotorWay Scorpion I, derived from the Schramm Scorpion. The Scorpion I had very low life limits on major components. This was the main weakness that needed to be addressed with further research and development. An improved version of the Scorpion, the Scorpion Too was introduced in 1971. The RotorWay Scorpion Too had an expanded fuselage structure with a two-seat fibreglass cabin enclosure and a 105kW Evinrude marine engine. In 1974, RotorWay Aircraft embarked on a major redesign with the goal of reducing the amount of maintenance time required for every hour of flight. First to be addressed was the elimination of the inefficient 2-stroke engine. Unable to find an engine manufacturer to make a 4-stroke engine suitable for a helicopter, RotorWay developed and produced their own engine; an aspect of the company that is unique to this day. Called the RW133, the new 4-stroke engine had the added power RotorWay wanted for its helicopters. Scorpion helicopters fitted with the new engine were called the Scorpion 133. In the 1980s a substantial redesign effort produced the aerodynamically improved RotorWay Exec series. In the late 80's, RotorWay created the Elite, a larger, attractive two-place helicopter. After selling three Elite helicopters, the company finally succumbed to financial challenges. RotorWay Company Inc. was purchased by a former customer, John Netherwood, a businessman from England and re-established as RotorWay International on 1 June 1990. The new company recognized the design hurdles of the Elite and promptly set out to making the proven Exec a better aircraft to build and fly. However slower and heavier than the Elite, the Exec model proved to be a better aircraft to sell and in 1990 the RotorWay Exec 90 was launched. In August 1994, Exec 162F was introduced and replaced the Exec 90. In 1996, the assets of RotorWay International were acquired by company's employees, who are current owners. In July 2007, RotorWay announced the development of the A600 Talon. The A600 Talon features an updated FADEC system, an all-glass cockpit, a cog-belt replacing the primary drive chain, and a larger landing gear, among other features. However the experimental kit helicopter market and the non-type certified markets have been very loyal markets for Rotorway, the RotorWay has established a factory in South Africa that manufactures ready-made helicopters in addition to kits. RotorWay has also begun the process of expanding into the certified helicopter market, and plans on making major changes, including the creation of a separate engine manufacturing company.

RotorWay Exec 162F c/n 5128 was built in Denmark by Jrgen Skov Nielsen in 1998. However in 1997, this RotorWay Exec 162F was registered OY-9305 in Denmark with Jrgen Skov Nielsen, it is not sure if this registration was ever used on the helicopter. In 1999, the RotorWay Exec 162F was noticed first with registration OY-HJS. In September 2016, the Rotorway Exec 162F was hoisted on board of the yacht "Christina Onassis"; placed on airbags and firmly fixed at the rear deck of the yacht. The "Christina Onassis" is a former yacht of the Onassis family and nowadays in use as a yachthotel and for cruises from Rotterdam. However the officially home port of the ship is Vanuatu, it is docked in the Entrepothaven, part of City Marina Rotterdam. The callsign of the yacht is YJTB4 and therefore YJTB4 is painted at the metallic tail of the helicopter. There can be flown with this helicopter from the yacht. The fence around the rear deck can be removed easily and the deck can expand backwards into an helicopter platform. In the winter there is no engine in the RotorWay Exec 162F, but the helicopter has a new engine. The move of the helicopter to / from the helideck is done with the crane of the yacht. If there is going to be flown with the helicopter it will be registered first in the USA and the first time the N-registered helicopter will fly from an airfield. Currently, the helicopter is still registered OY-HJS in Denmark with Jrgen Skov Nielsen, Sunds.
