HILLER SERIES

Hiller Helicopters for Sale — California Pioneers of Rotary Wing Aviation

The name Hiller is woven into the earliest chapters of American helicopter history. Stanley Hiller Jr. built his first successful coaxial helicopter — the XH-44 Hiller-Copter — in 1944 at the age of seventeen, making him one of the youngest serious helicopter designers in history. From that beginning in Berkeley, California, Hiller Helicopters grew into a significant manufacturer whose designs served the US military, law enforcement, agricultural operators, and private owners across three decades of production. The Hiller name stands for a particular breed of American helicopter engineering — mechanically honest, practically capable, and built to be maintained by people who work with their hands in the real world.

Key Hiller Models

• Hiller UH-12 (Model 360) — The helicopter that established Hiller's civilian reputation. Powered by a Franklin 6V4-200-C32 engine, the UH-12 earned FAA certification in 1948 and went on to serve as a primary military trainer (designated H-23 Raven by the US Army), an agricultural sprayer, a powerline patrol platform, and a flight training helicopter at schools across the United States. Its three-seat side-by-side-plus-rear or two-seat arrangement and open-frame design give it a timeless appearance that makes it immediately recognizable at airshows and fly-ins.
• Hiller UH-12E — A turbine-powered evolution using the Allison 250-C18 engine, bringing jet-smooth power to the UH-12 airframe and significantly improving hot-and-high performance for operators in mountainous or high-altitude environments.
• Hiller H-23 Raven — The military designation for the UH-12 family that served the US Army and other armed forces as a primary observation and training helicopter, accumulating a distinguished service record that included operations in Korea.
• Hiller FH-1100 — Hiller's most advanced design, developed from the OH-5A military observation helicopter program. The FH-1100 introduced a five-blade main rotor and turbine power to produce a fast, capable light turbine helicopter that competed directly with the Bell JetRanger. It is one of the rarest and most interesting light turbines available on the pre-owned market today.

The Hiller Rotormatic Control System

Hiller helicopters are distinguished by the Rotormatic paddle system — a set of small servo-rotor paddles mounted perpendicular to the main rotor blades that provide pilot control inputs through aerodynamic feedback rather than direct mechanical connection. This system gives Hiller helicopters exceptionally stable hovering characteristics and a predictable, forgiving control response that made them ideal training platforms. Pilots who have flown Hillers frequently cite the stability of the hover as one of the most distinctive and enjoyable aspects of the type.

Collecting and Operating Hiller Helicopters

Hiller helicopters occupy a special place in the collector helicopter market. They are old enough to qualify as genuine vintage rotorcraft with historical significance, yet young enough that airworthy examples can still be acquired and maintained without impossible parts sourcing challenges. The US Army H-23 Raven variants in particular attract military aviation historians and warbird collectors who want a flyable piece of Korean War-era aviation history. Agricultural UH-12s with their distinctive spray equipment tell the story of helicopter farming in the American West. Finding a Hiller for sale on Airplane Trade may lead you to one of these extraordinary machines — each with its own operational story.
