Redundancy Approach
Certification-level system redundancy should be taken from the FAA compliance record rather than inferred from the single-motor configuration; current public company material emphasizes motor simplicity and accepted design/test plans.
Range / Speed
Current company material emphasizes the 125 kW propulsion motor and training mission; PropulsionWatch has not normalized range/speed here without a current certification-basis source.

The eFlyer 2 prototype made its first flight on 24 September 2026 from Centennial Airport, Colorado, under an FAA special airworthiness certificate. It is not type certificated; Bye is pursuing FAA Part 23 certification.
Expand the flight envelope and move from development flying to FAA-witnessed compliance testing.
eFlyer 2 is a two-seat all-electric trainer being developed by Bye Aerospace for FAA Part 23 certification.
Bye currently advertises a single 125 kW electric motor, composite airframe and Garmin avionics for the eFlyer training platform.
Bye says design and test plans for Part 23 certification have been accepted. In September 2026 the prototype received an FAA special airworthiness certificate, and on 24 September 2026 it made its first flight from Centennial Airport near Denver, flown by chief test pilot Elliot Seguin.
The intended market is flight training, where Bye positions electric propulsion around lower operating cost, noise and maintenance burden.
Experimental airworthiness approval does not certify the aircraft type. Formal FAA compliance demonstration, Type Certificate issuance, production approval and delivery readiness remain separate gates.
