Electric Constant Speed Propellers for Experimental and Light Sport Aircraft

Designed to ASTM F2506 (Standard Specification for Design and Testing of Light Sport Aircraft Propellers), AXSport Aviation’s range of lightweight three-blade electric constant speed propellers are designed for non type certified aircraft. The microprocessor controller adjusts the blade pitch automatically in order to maintain a chosen RPM, irrespective of the amount of engine torque being produced or the airspeed.

The AXSport constant speed propellers are simple to operate, weigh little more than ground adjustable propellers and are priced to make great performance affordable. Fly with the maximum performance possible from your aircraft. Full engine power is now available for take-off, climb, cruise and effective propeller braking is available to slow the aircraft down on landing.

Handcrafted for Strength. Tested in the Air. Built for Reliability.

• 3 blade Electric & Hydraulic Constant-Speed Propellers for Experimental & Sport Aircraft
• Designed for 80hp – 160hp Rotax engines and derivatives
• Hydraulic and electric options for Lycoming engines up to 180hp
• Designed around ASTM Specifications, the lightweight three-blade propellers are designed for non-type certified aircraft
• Precision Engineered – Handcrafted for Low Vibration & Maximum Performance
• Thousands of Flight Hours – Proven Beyond ASTM Standards
• More Affordable, More Reliable, Low Maintenance

The Most Practical Constant-Speed Upgrade

Most constant-speed propellers are either too complex, too fragile, or too expensive. AXSport is different. We designed a propeller that balances strength, precision, and affordability—so you can fly with confidence and keep costs low.

• Engineered for Strength & Durability – Designed to last, tested in real-world flight conditions.
• Handcrafted for Low Vibration – Precision-manufactured components reduce wear & tear.
• Low Maintenance, Low Operating Costs – Fewer moving parts, less servicing needed.
• More Affordable Than Most Constant-Speed Solutions – High performance without the high price.

Designed for serious pilots who demand reliability without unnecessary complexity.
"We believe in our propellers, and we prove it. Every AXSport prop comes with a 1,000-hour limited warranty, backed by thousands of hours of real-world operation. We stand behind our propellers with a commitment to safety, support, and customer satisfaction."

Engineered for Strength – Built to Last

Many propellers compromise strength for weight savings. AXSport uses a different approach. We engineer for durability and reliability first—because safety and longevity should never be sacrificed

Strong Carbon Epoxy Blade and Spinner Construction – Designed to handle real-world stress.

Robust aerospace grade aluminium hub - CAD/CAM designed hubs are CNC machined in-house
ensuring that the critical tolerances affecting smooth operation and perceived vibration are precisely met.

Lower Vibration = Less Engine Wear – Handcrafted to precision tolerances for smooth, efficient flight.

No Fragile Electronics or Complex Hydraulics – Smart engineering means fewer failure points.

Extreme Condition Performance – Trusted in rough-field, aerobatic, and high-performance environments.

SERVICE SCHEDULE

The propeller is maintained on-condition. The condition of the propeller is monitored by a combination of pilot monitoring during operation and regular inspection as detailed below. The propeller contains no life-limited parts. In all cases the original propeller operations manual, or the latest one issued, is the governing document for service intervals for each specific propeller by serial number.

MODELS

The 3-blade, tractor propellers are suitable for 80hp – 141 hp Rotax engines and up to 180 hp Lycoming engines. The propeller system includes a carbon fibre spinner, carbon fibre backing plate, constant speed controller, wiring loom and installation hardware. Propeller lifetime is not specified if mandatory periodical inspections are performed at specified intervals. TBO is 1000 operational hours or 60 months. Maximum propeller diameter is 74”.

Proven Performance – Real-World Tested Beyond ASTM F2506

AXSport propellers have logged thousands of hours across hundreds of aircraft, proving unmatched durability and performance—far beyond any certification checklist.

• Top-hour propellers approaching 1,000 hours with zero failures
• Flown in aerobatics, STOL, cross-country, and high-altitude conditions
• Surpassed ASTM F2506 guidelines through real-world testing in extreme conditions

"AXSport propellers have logged thousands of flight hours across hundreds of aircraft, with top-hour props reaching nearly 1,000 hours. AXSport’s testing goes beyond paperwork—we validate our propellers in the air, through real-world flight data, in a variety of aircraft and flying conditions. We don’t just pass tests—we prove performance in the air."
