Hill Helicopters: designing a chopper like a supercar
Jason Hill has spent years redefining rotorcraft, and his HX50 helicopter is poised to create a fresh chapter in aviation.
The HX50 introduces a completely new design, blending innovation with practicality. Its high-inertia three-blade rotor system promises a cruising speed of 160 mph and an impressive 800-mile range. While its advanced avionics, sleek styling, and spacious interior set it apart, the real game-changer is its $798,000 price tag—about a third less than similar models.
“The machine is designed to feel like a supercar,” says Hill. “It also aims to simplify flying more than ever before.”
“The machine is designed to feel like a supercar,” says Hill. “It also aims to simplify flying more than ever before.” A carbon-fiber monocoque frame—a first for lightweight helicopters—and a proprietary touchscreen interface highlight its cutting-edge engineering. Safety features like roll cages, impact-absorbing seats, and crash-resistant fuel tanks and windows are typically reserved for larger, costlier aircraft.
Hill’s vision was sparked by childhood memories of the supersonic helicopter fr om Airwolf . Over 25 years, he meticulously crafted the HX50, unveiling its concept in 2020. Along the way, he collaborated with industry leader AgustaWestland, earned a Ph.D. in computational aerodynamics, and founded Dynamiq Engineering, which provided technical expertise and financial backing.
The idea stemmed from Hill’s frustrations as a pilot, identifying shortcomings in current offerings: limited range, outdated engines causing excessive noise, and a lack of refinement. Despite its forward-thinking design, skepticism persists.
“Aviation often chews up newcomers,” notes Brian Foley, an industry analyst. He points out the challenges start-ups face due to the high costs of development. Still, Foley acknowledges the HX50’s potential, noting the absence of clean-sheet designs in the light helicopter segment for years. He references successes like Epic Aircraft’s E-1000 turboprop and Kopter’s SH09, acquired by Leonardo in 2020. “If others succeeded, why not Hill?”
Critics, however, have flagged the GT250 engine as a potential weak point. “Helicopter manufacturers usually rely on aviation-specific engine suppliers,” explains Jean-Marc Youkhana, founder of Uplifting Aviation. “This engine comes from a non-aviation company and isn’t certified yet. That’s a gamble.”
Flight testing, initially planned for 2024, has been pushed back—not due to engine issues but because of delays in building a facility for in-house component production. “This approach allows us to build exactly what customers want at a cost traditional supply chains can’t match,” Hill emphasizes.
To reduce costs further, the HX50’s business model includes a 10-day “build school,” wh ere owners assist in assembling non-technical parts. This qualifies the helicopter for the “amateur-built” category, trimming expenses and potentially accelerating certification. Hill envisions the HX50 as so appealing that it could inspire people to take up flying again.
Of the 1,300 units pre-sold, 30% were purchased by first-time aircraft buyers. Testing is now scheduled for later this year, with production slated for 2026.
