Robinson R44 helicopters for sale in the UK: new Raven I, Raven II and Cadet from HQ Aviation, authorised dealer at Denham Aerodrome, London
Frank Robinson's four-seat masterpiece, the most-built civilian helicopter in history, and still the most sensible way into ownership.
Simple. Dependable. Proven.
Frank Robinson founded Robinson Helicopter Company in his Palos Verdes living room in 1973 with a single obsession: a civilian helicopter normal people could actually afford to own and fly. The R44, first flown in 1990 and certified in 1992, is the fullest expression of that idea, and the world's best-selling general aviation helicopter every year since 1999.
More than 6,500 have been built. Parts are available globally, mechanics everywhere are trained on it, and direct operating cost sits below £230/hr. which is why it remains the smartest first helicopter most private buyers and schools will ever purchase. In March 2026 Robinson added the new R44 Utility interior package, bringing factory-built agricultural and doors-off capability to the same proven airframe.

R44 Variants
R44 Raven I
The affordable four-seat classic.
The original R44: a carbureted Lycoming O-540 driving hydraulic controls and a proven two-blade rotor system. The Raven I remains the most affordable route into genuine four-seat helicopter ownership, and HQ Aviation places new orders direct with Robinson in Torrance.
- Lycoming O-540 carbureted engine
- Hydraulically-assisted controls
- Lowest acquisition cost in the range
- 2,400 lb maximum gross weight
- Carb-heat assist system standard
Technical Specifications
Lowest Operating Cost
The R44 is the most budget-friendly route into four-seat helicopter ownership. Fuel dominates direct operating cost, reserves are predictable, and parts are available from any Robinson service centre worldwide.
Four-Seat Utility
A genuine four-seat cabin with removable dual controls, full dual-pilot training capability, and enough useful load for two adults plus luggage or three passengers on shorter trips.
Proven Worldwide
Over 6,500 delivered and in active service on every continent. The most-produced civilian helicopter of its era, with the deepest global support network in piston rotorcraft.
Lycoming Reliability
Every R44 flying today is powered by a derated version of the Lycoming IO-540, one of general aviation's most respected piston engines. This partnership is the single biggest reason R44 ownership costs are as predictable as they are.
Lycoming has built horizontally-opposed aircraft engines since the 1930s, and the O-540/IO-540 family is the workhorse that flies everything from Cessna 206s and Piper Senecas to the R44. Frank Robinson specified it for exactly the reasons he specified every component on the airframe: proven, serviceable by any competent mechanic anywhere in the world, and affordable to overhaul when the time comes.
Proven Powerplant
The Lycoming IO-540 is one of general aviation's most trusted engines: a fuel-injected, air-cooled flat-six with decades of service across fixed-wing and rotary aircraft worldwide.
Derated For Reliability
The AE1A5 can produce up to 300 hp at full throttle, but Robinson derates it to 245 hp for take-off and 205 hp continuous. Running well below its capability is exactly why the R44 has such a long, reliable service life.
Torque-Rich Design
Spinning a 33-foot main rotor plus tail rotor demands torque, not just horsepower. The IO-540 delivers nearly 800 ft·lbs, the muscle that makes the R44 smooth in every flight regime.
2,200-Hour TBO
Factory time-between-overhaul is 2,200 hours or 12 years, a direct reflection of how gently the airframe treats the engine, keeping ownership costs predictable year after year.
Roughly £170–£230 per hour direct operating cost
Robinson publishes an Estimated Operating Cost sheet for every R44 variant each year, and the figures line up with what owners actually see on the invoice. Fuel is the single largest line, overhaul reserves are fixed and published, and parts availability through the global dealer network keeps AOG time short. All of which is why the R44 is the most straightforward piston helicopter on the market to budget, finance and run.
- ~15 US gal/hr fuel burn, the dominant line item
- Predictable reserves for overhaul & maintenance
- Global parts availability, any field, any country

R44 buyer FAQs
What R44 variants can I buy new?
Three: the four-seat Raven I (carburetted Lycoming O-540), the four-seat Raven II (fuel-injected IO-540, 245 hp for take-off and 205 hp continuous, better hot-and-high performance), and the two-seat Cadet trainer. All are ordered factory-new through HQ Aviation, a Robinson authorised UK dealer.
How much does a new Robinson R44 cost?
Robinson’s indicative factory list prices are around $520,000 for the Cadet, $553,500 for the Raven I and $646,000 for the Raven II, before options and VAT. Live pound prices for every variant are on our helicopter sales page.
What is the R44 overhaul clock?
Every R44 reaches a mandatory overhaul at 2,200 flight hours or 12 calendar years, whichever comes first. Remaining life on that clock is the single biggest driver of a used R44’s value.
What’s the difference between the Raven I and Raven II?
The Raven II’s fuel-injected IO-540 gives more take-off power (245 hp against the Raven I’s 225 hp), a slightly higher cruise and better hot-and-high performance than the Raven I’s carburetted O-540, with corresponding differences in price and useful load.
Can I learn to fly in the R44 I buy?
Yes. Many owners train for their PPL(H) at HQ Aviation on the same type they own. Training and ownership run from the same hangar at Denham Aerodrome, 30 minutes from central London.
Should I buy a new or used R44?
New buys the full 2,200-hour/12-year clock, warranty and your exact specification. A good used example with strong remaining overhaul life is the value play, and our used R44 buyer’s guide covers exactly what to check.
