More civilian helicopters have been built to the Robinson R44 design than any other. Since the first Astro rolled out of Torrance in 1992, over 6,000 have been produced. They train helicopter pilots on every inhabited continent. They work pipelines in Texas and musters in Queensland. They tour tourists over Manhattan and the Grand Canyon. They are the Honda Civic of the helicopter world: modest by aviation standards, thoroughly proven, parts-available everywhere.

They are also genuinely complex machinery with ownership economics that surprise buyers approaching them from fixed-wing backgrounds. The 2,200-hour mandatory overhaul is a financial event unlike anything in piston aeroplane ownership. Understanding it is the prerequisite for any serious R44 purchase.

Our database records 824 completed R44 sales. Here is what those transactions — and Robinson's own official cost figures — tell you before you buy.

The Variants: What You're Choosing Between

The R44 family has evolved considerably since 1992. There are meaningful differences between variants.

R44 Astro (1992–1998): The founding model, powered by a Lycoming O-360 (carbureted, 225hp at sea level, derated to 183hp for continuous operation). Very few trade today — 2 in our database, averaging $229,000. Largely a collector and training curiosity at this point.

R44 Raven I (2000–present): The first significant redesign, retaining the carbureted O-540 Lycoming (225hp, derated) but with a substantially updated airframe, hydraulic controls, and IFR-capable instrument panel option. This is the entry-level R44. 188 sales in our database, averaging $326,000.

R44 Raven II (2002–present): The dominant variant, powered by a fuel-injected Lycoming IO-540 (245hp, derated) with higher density altitude performance, fuel injection reliability, and better hot-and-high operation. This is what most serious buyers want. 456 sales in our database, averaging $479,000. New examples currently list at $700,000–$838,000.

R44 Cadet (2016–present): A two-seat trainer version of the Raven II platform, designed specifically for flight schools. Lower maximum gross weight, no rear seats, dual controls standard. Our data shows 57 Cadet sales averaging $437,000. Not the right aircraft for personal use — buy a Raven II instead.

R44 Clipper I/II: The floatplane variant, fitted with Robinson's own pop-out floats. The Clipper II (245hp, fuel-injected) is the current version. 66 Clipper II sales in our database average $500,000. Essential for water operations; unnecessary weight and complexity for land use.

What You'll Pay: Price Data from 824 Sales

Variant	Sales	Avg Sale Price	Range
R44 Raven I	188	$326,000	$85k–$654k
R44 Raven II	456	$479,000	$105k–$1M
R44 Cadet	57	$437,000	$289k–$553k
R44 Clipper II	66	$500,000	$94k–$822k

The price curve for the Raven II tells the market story clearly. Our year-by-year data shows:

Model Year	Avg Sale Price	Sales
2004–2007	$341,000–$435,000	156 sales
2010–2013	$298,000–$454,000	61 sales
2015–2017	$379,000–$424,000	78 sales
2018	$509,000	18 sales
2021–2022	$577,000–$610,000	22 sales
2023–2024	$609,000–$612,000	106 sales
2025	$689,000	29 sales

The COVID-era surge pushed R44 prices to new highs in 2021–2022, and they have broadly held. A 2020–2023 R44 Raven II is now a $600,000+ purchase. New aircraft list at $700,000–$838,000. These are not cheap helicopters.

Currently on the market: Active listings include a 2024 Raven II at $819,000 (100 TT), a 2025 Raven II at $680,000 (4 TT, essentially new), and a 2026 new-delivery Raven II at $701,000–$721,000. At the older end, mid-2000s examples start below $350,000 — but time-before-overhaul changes everything (see below).

The 2,200-Hour Overhaul: The Number That Defines R44 Economics

If you come from fixed-wing ownership, Robinson's life-limited component system will require a mental adjustment. The R44 is not an aircraft where you run the engine to TBO and overhaul it. The entire helicopter has mandatory life limits.

At 2,200 hours total time, the R44 requires a comprehensive overhaul of all life-limited components. This is not optional — it is an airworthiness requirement. Robinson Helicopter Company publishes official pricing.

Robinson's official 2025 cost figures for the Raven II at 2,200 hours:

Item	Cost
Aircraft overhaul parts kit (life-limited components)	$193,700
Engine exchange (IO-540 factory overhaul)	$85,700
Labour (225 man-hours × $125/hr)	~$28,125
Total 2,200-hour overhaul	~$307,500

That is not a typo. The overhaul on an R44 approaches the purchase price of a well-maintained used example.

This is why time-before-overhaul (TBO) is the most important variable in any R44 purchase. An aircraft with 200 hours remaining until the 2,200-hour event needs $307,000 of work in roughly one season of typical flying. An aircraft with 1,800 hours remaining has that cost seven to eight years away at typical owner-pilot utilisation (200–300 hours per year).

Robinson recommends an overhaul reserve of $139.78 per flight hour (their 2025 official figure), which breaks down as:

Engine overhaul reserve: $38.95/hr
Aircraft overhaul parts: $88.05/hr
Overhaul labour: $12.78/hr

At 200 hours per year, that is $27,956 going into overhaul reserves annually. This is money you must budget — it is not optional maintenance that you can defer.

Running Costs: What Robinson's Own Numbers Say

Robinson Helicopter Company publishes an official Estimated Operating Cost document, updated annually. The 2025 figures for the Raven II at typical utilisation:

Cost Item	Per Hour
Fuel (15.0 gph at $6.05/gal)	$90.75
Oil	$2.60
Periodic inspections	$37.50
Unscheduled maintenance	$13.80
Direct operating cost	$144.65/hr
Overhaul reserve (all components)	$139.78/hr
Total operating cost	$284.43/hr

Direct costs exclude insurance; overhaul reserve is manufacturer's recommended figure.

At 200 hours per year, direct annual operating costs (excluding overhaul reserve and insurance) run approximately $28,930.

Add the overhaul reserve ($27,956) and you are at $56,886 per year before insurance and hangar.

Annual insurance for a private R44 owner with commercial-rated or private helicopter certificate typically runs $8,000–$14,000 for hull and liability combined, depending on hull value and pilot experience.

Hangar or tie-down: Helicopter hangars run $400–$900 per month depending on location. Outdoor tie-down is cheaper but weather exposure accelerates wear on rotor components.

Realistic total annual cost at 200 hours: approximately $75,000–$85,000 per year including insurance and reasonable hangar costs, excluding the overhaul reserve if kept separate.

The Raven I vs Raven II Decision

The price gap between a Raven I and Raven II of similar vintage is typically $120,000–$150,000. Is the upgrade worth it?

Buy the Raven II if: You fly at elevation, in hot climates, or want the reliability of fuel injection. The IO-540's additional 20hp and fuel injection make a meaningful difference above 3,000–4,000 feet density altitude. Hot and high performance is appreciably better.

The Raven I is acceptable if: You fly at low altitudes in mild climates, budget is a hard constraint, and you have a local mechanic comfortable with carbureted O-540s. The Raven I is a proven, capable helicopter — it just operates a narrower performance envelope at extremes.

Note that the Raven I and Raven II share the same 2,200-hour life-limit structure, and overhaul costs are similar (the IO-540 exchange is slightly more expensive than the O-540, but not dramatically). The decision is primarily operational rather than cost-based.

What to Check Before Buying

Time before 2,200-hour overhaul. This is the most important number on the logbook. Calculate the cost and budget impact before making any offer.

Annual inspection history. The R44 requires a 100-hour inspection (or annual for private use) that covers the rotor system, gear box, engine, and controls. Ask for the last three inspection records. Gaps in the inspection history are a red flag.

Rotor track and balance history. An improperly tracked or balanced main rotor damages the airframe over time. Look for documentation of track and balance work.

Avionics and instrument panel vintage. Mid-2000s examples often have older avionics. A full glass panel retrofit (G500H TXi, GTN 750) adds $30,000–$60,000. Factor this into the comparison between an upgraded older aircraft and a lower-spec newer one.

Training history. R44s used in flight schools accumulate hours rapidly (400–600 hours per year is normal) and receive harder treatment than privately flown examples. Training school hours are not disqualifying, but inspect more carefully for wear on controls, seats, and cabin.

Where it was operated. Salt air exposure accelerates corrosion on rotor heads, transmission components, and airframe. An R44 from coastal Florida or a marine environment needs more careful inspection than one from dry, inland operation.

New vs Used: What the Market Says

The new R44 Raven II lists at approximately $700,000–$838,000 in 2026. A 2019–2021 example with 500–700 hours sells for $500,000–$600,000, leaving $200,000–$300,000 in potential savings — but with the 2,200-hour event accordingly closer.

The economics most often favour buying a 2016–2019 example with 400–800 hours remaining before the overhaul and budgeting the overhaul reserve diligently. This typically means purchasing in the $450,000–$550,000 range, running the aircraft for three to five years of normal flying, and then either selling before the 2,200-hour event or funding the overhaul.

Selling before the 2,200-hour event is a valid strategy — the used market has a price tier structure that discounts heavily as aircraft approach the overhaul milestone. A buyer purchasing a high-time R44 at a discount is essentially pricing in the work coming due.

Is the R44 the Right Helicopter for You?

The R44 suits a specific kind of buyer: someone who wants a four-seat helicopter with good range (approximately 300nm), proven reliability, and a deep worldwide support network, and who is prepared to budget seriously for the 2,200-hour overhaul cycle.

It is not the right aircraft for buyers expecting helicopter ownership to cost roughly the same as fixed-wing. It is more expensive to operate per hour than a comparable fixed-wing, and the overhaul cycle is financially demanding in a way that piston aeroplanes simply are not.

For buyers who understand and budget for those costs, the R44 is an exceptional aircraft. The worldwide parts and maintenance network, Robinson's conservative engineering approach, and the deep operator community make it one of the most supportable small helicopters ever built.
