Choosing between the Bell 505 Jet Ranger X and the Robinson R66 Turbine represents one of the most common dilemmas facing buyers in the light turbine helicopter market. Both aircraft occupy a similar niche as five-seat, single-engine turbine helicopters, yet they take distinctly different approaches to design, performance, and value. This comprehensive comparison breaks down everything you need to know to make an informed decision.

Performance Analysis
Power and Speed
The Bell 505 holds a clear advantage in raw power with its 504 shp Safran Arrius 2R engine compared to the R66 300 shp Rolls-Royce RR300. This translates to better high-altitude performance, improved hot-and-high capabilities, and a slight edge in cruise speed at 125 knots versus 120 knots. The Bell dual-channel FADEC system also provides smoother power management and enhanced safety margins.
Range and Efficiency
Interestingly, the less powerful R66 actually wins the range battle with 350 nm compared to the Bell 306 nm. This comes down to fuel efficiency – the R66 sips just 23 gallons per hour while the Bell 505 burns approximately 30 gallons hourly. For operators prioritizing fuel costs and extended missions, the Robinson offers a compelling advantage.
Payload Capability
The Bell 505 higher useful load of 1,500 lbs versus 1,420 lbs gives it more flexibility for utility operations. Combined with its 22-square-foot flat floor cabin and 18-cubic-foot luggage bay, the Bell provides superior cargo-carrying versatility for commercial operators.
Cost Analysis
Acquisition Costs
The Robinson R66 wins decisively on purchase price. New R66 models range from approximately $1.4 million to $1.7 million depending on configuration, while a new Bell 505 commands $2.1 million to $2.3 million. That is a potential savings of $500,000 to $700,000 – significant capital that could fund years of operating costs.
The pre-owned market reflects similar ratios. Used R66s typically trade between $500,000 and $900,000, while pre-owned Bell 505s range from $1.1 million to $1.5 million.
Operating Costs
The R66 maintains its cost advantage in daily operations. Lower fuel burn (23 vs 30 gallons/hour) translates to meaningful savings over time. At current Jet-A prices, operators could save $50-70 per flight hour on fuel alone. However, the Bell longer 3,000-hour engine TBO compared to the R66 2,000-hour interval partially offsets this through reduced overhaul frequency.
Insurance costs tend to favor the Robinson due to its lower hull value and the company extensive safety record with the R44 and R66 platforms.
Technology and Avionics
The Bell 505 features the Garmin G1000H NXi integrated flight deck as standard equipment, representing the most advanced avionics package in the light single-engine turbine category. This system includes dual 10.4-inch displays, synthetic vision, and helicopter-specific features that enhance situational awareness.
The R66 offers the Garmin G500H display system with available Genesys Aerosystems HeliSAS autopilot. While capable and modern, it does not match the integration level of the Bell glass cockpit solution.
Build Quality and Support
Bell brings decades of military and commercial helicopter manufacturing expertise to the 505, reflected in its metal and composite construction and robust component design. The company global support network spans over 100 countries with extensive parts availability.
Robinson has built its reputation on value and reliability. With over 1,500 R66s delivered, the platform has proven itself in diverse operating environments. Robinson factory-direct support model keeps parts costs lower, though service network coverage is not as extensive as Bell.
The Verdict: Which Helicopter Wins?
Choose the Robinson R66 if:
- Budget is your primary concern
- You prioritize fuel efficiency and range
- You are a private owner or small operator
- Lower operating costs outweigh premium features
- You value the Robinson ownership community
Choose the Bell 505 if:
- You need maximum performance and payload
- Advanced avionics and technology matter
- You operate in demanding environments (hot/high)
- Commercial operations require premium image
- Longer engine TBO intervals benefit your mission profile
Both helicopters excel in their respective value propositions. The R66 represents the most affordable entry point into turbine helicopter ownership, while the Bell 505 delivers premium performance and technology at a higher price point. Your mission requirements, budget constraints, and operational priorities will ultimately determine which light turbine helicopter wins for your specific needs.
