Stephan Boutenko, Alternair President and founder, seeks a Light Sport Aircraft alternative, an airplane looking like an LSA, but loaded with features that will allow it to keep pace with the rapidly changing options coming to electric flight. Inspired by Yuneec’s E-430 but disappointed by its slow cruising speed, Boutenko was determined to create something more in line with LSA performance criteria. He also wanted to take advantage of the knowledge he had gained from years of experience with heavier aviation to create an integrated system that would allow flexibility and expandability in the development of his airplane. Unabashedly conventional in appearance, the low-wing, tricycle geared monoplane is conceived to make a pilot transitioning from an internal combustion powered machine feel right at home. The motor control electronics (MCE), for instance, are redundant, and the key-operated switch on the instrument panel has an OFF/ L(EFT MCE)/R(IGHT MCE)/BOTH function, matching the ignition switch for dual magnetos. Beyond that bow to tradition, …
