Our Take on Elroy Air

The Elroy Air team has recruited a wide variety of expertise and perspectives, with employee backgrounds ranging from academia to both large an small aerospace-focused companies. Many members of the team have prior experience growing and selling hardware startup companies, which will prove to be beneficial in the event that Elroy Air is situated for a strategic or financial acquisition. The company's aircraft, the Chaparral, is wisely applicable to a range of industries and could be implemented with slightly more limited scrutiny than a passenger vehicle, given that it is planned to carry exclusively cargo. The 1,215-pound vehicle also boasts an impressive max payload weight of up to 500 pounds, and its hybrid-electric propulsion system continues to be flight tested at McMillan Airfield in Camp Roberts, CA.
