Electric Aircraft Advance, but Light-Sport Buyers Still Face Certification and Cost Questions

Two electric-aircraft developments reported this week offer a useful snapshot of where light aviation is heading—and how much work remains before new designs become everyday ownership options. Skyfly has secured funding to pursue light-sport approval for its two-seat Axe vertically capable aircraft, while Bye Aerospace’s full-scale eFlyer 2 prototype has completed its first flight.

The programs address different markets and follow different approval paths. Skyfly is targeting private owners through the FAA’s updated light-sport framework. Bye Aerospace is pursuing Part 23 certification for a training aircraft. Together, they highlight the potential for electric propulsion to broaden aircraft choice and reduce operating expenses, without yet establishing what customers will experience in routine service.

Skyfly funds its light-sport ambitions

Skyfly announced a $10 million seed round on October 20, led by HICO Investment Group with participation from Archangel. Aviation Week reported that the funding is intended to take the Axe through FAA Part 22 approval as a light sport aircraft.

According to DRONELIFE, the company plans to complete FAA light-sport certification and expand manufacturing capacity in the United Kingdom and United States. First customer deliveries are planned for 2027. Skyfly reports more than 100 prototype flights, experimental flight permits in both countries and an order book of 61 private customers worldwide.

The Axe combines vertical takeoff and landing with wing-borne forward flight. Its eight fixed-angle electric motors provide vertical-flight capability, while its fixed wings provide lift in cruise. It can also use conventional runways.

Skyfly’s published figures include a range exceeding 100 miles, endurance of 60 to 90 minutes, a cruise speed of approximately 100 mph and a 200-kilogram payload. The company estimates operating costs at approximately $90 per flight hour. DRONELIFE explicitly describes these figures as company projections rather than independently verified operating results.

For prospective owners, the significance is the proposed route into private aviation rather than the commercial air-taxi market. Reporting on the MOSAIC framework describes expanded eligibility for electric propulsion, multiple motors and certain vertically capable aircraft. That creates a potential approval path; it does not mean the Axe is already approved for customer delivery. Experimental flight permits and a funded certification effort remain distinct from completed approval.

eFlyer 2 begins another stage of testing

AOPA reported on October 22 that Bye Aerospace’s full-scale eFlyer 2 prototype made a six-minute first flight from Centennial Airport in Colorado on September 17, with chief test pilot Elliot Seguin at the controls.

That milestone should not be confused with the 2018 first flight of the Sun Flyer 2, a modified light-sport aircraft used as a proof of concept. The program was renamed eFlyer in 2019. Bye Aerospace applied for an eFlyer 2 type certificate in 2018, and the FAA accepted its certification plans in 2023.

The current aircraft uses a composite structure, a 125-kilowatt electric motor and a battery system with about 90 kilowatt-hours of capacity. Flight testing continues, including work still needed to evaluate endurance and high-altitude performance.

Bye Aerospace estimates operating costs of $35 to $40 per flight hour, including electricity, maintenance and battery replacement. Its claim of savings reaching 80 percent remains conditional on those estimates holding up. These are projected operating costs, not an announced flight-school rental rate.

What pilots should watch next

Charging arrangements deserve attention alongside aircraft specifications. Bye Aerospace is working with Electro.Aero on a system that could serve aircraft through cables reaching as far as 100 feet from chargers near a ramp or hangar edge. One charger can charge two aircraft simultaneously, and the company recommends one charger for every six airplanes.

That work illustrates why electric-aircraft ownership involves more than selecting an airframe. Owners and schools will need to assess charging access, aircraft availability between flights and demonstrated endurance against their intended missions.

The next meaningful milestones are therefore completed approvals, fuller flight-test results and operating experience. This week’s announcements show progress toward those goals—not yet proof that projected costs, performance or delivery schedules will be achieved.
