This Shergood B2-B is an SL reproduction of the classic Brantly B2-B helicopter. The Brantly B2 was originally introduced in the late 1950s and was later upgraded to the B2-A and then the B2-B. It uses a 180hp fuel-injected four cylinder horizontally opposed Lycoming IVO-360 engine, a vertical variant of the engine commonly found in the Cessna 172.

The design won the Grand Award at the 1947 World Inventors' Congress. However the future of cheap and plentiful air transportation was not to be, and further work on the UH-4 was halted. The Uh-4 was Hiller's final coaxial design, before inventing the "Rotormatic" control scheme with servo-paddles, for his follow on UH-5, which became the basis for the Hiller 360, The first Helicopter to cross the United States in 1948. this was further developed as the UH-12, which became the OH-23 for the U.S. Army in 1948.
The SA-FE (Shergood Aviation Flight Engine) engine driving this virtual reproduction is the most advanced and realistic in SL. It was designed and created by an RL helicopter pilot. The engine is purely physics based and features independent control of cyclic, collective, throttle and anti-torque pedals enabling true power-off autorotations. Features include:

The UH-4 is a two place, coaxial rotor design, powered by a 150 hp Lycoming O-290-0 carburetted engine. It has a rotor span of 33 feet (10.08m). It has a top speed of 100 mph, and a cruising speed of 75 mph, and a range of 200 miles.

This model is a recreation of the UH-4 prototype, currently residing in the Hiller Aviation Museum at the San Carlos Airport in California. The UH-4 was Stanley Hiller's fourth helicopter design, following his successful XH-44,the first successful coaxial rotor design. The UH-4 was designed in 1946, as a bid for the future when thousands of U.S. servicemen, trained to fly in the Second World War, might want to buy an inexpensive helicopter to fly to and from their jobs, or away from the city on weekends. It was small, and light and could be moved around easily. it had minimal instrumentation and a nearly "turn key" operation. at the time of it's design, Henry J. Kaiser was partnered with Hiller, forming a company named United Helicopters, and he backed the young Stanley Hiller's efforts at the time. Hiller demonstrated the helicopter at a shareholder's meeting held at the football field of Aragon High School, in San Mateo California, showing the effect of balanced controls and ease of use, by towing the hovering helicopter around the field by a rope, while the pilot sat with his arms crossed and his feet off the pedals, displaying the balanced controls that Stanley Hiller insisted on.

The design won the Grand Award at the 1947 World Inventors' Congress. However the future of cheap and plentiful air transportation was not to be, and further work on the UH-4 was halted. The Uh-4 was Hiller's final coaxial design, before inventing the "Rotormatic" control scheme with servo-paddles, for his follow on UH-5, which became the basis for the Hiller 360, The first Helicopter to cross the United States in 1948. this was further developed as the UH-12, which became the OH-23 for the U.S. Army in 1948.

The UH-4 is a two place, coaxial rotor design, powered by a 150 hp Lycoming O-290-0 carburetted engine. It has a rotor span of 33 feet (10.08m). It has a top speed of 100 mph, and a cruising speed of 75 mph, and a range of 200 miles.
