Mike Friend, retired Technology Director for Boeing Aircraft, and Gabriel DeVault, head of drivetrain development for ZeroAvia, are putting a Zero motorcycle motor into Mike’s Spark Solo.  There are perhaps dozens of Zero motors flying today, and the 42-pound unit has evolved to powering even two-seat motorgliders like Gabriel’s Sonex Xenos. An Ambitious Project Mike came up with the Spark Solo design as a way to, “Encompass the design process” as well as the “piloting and fabricating” aspects of a project.  He wanted to, “Define an airplane uniquely designed around electric propulsion,” noting that, “Past efforts have almost always been adaptations of internal-combustion powered airplanes.”  To help forward his design, Mike has been working with his local EAA chapter, for which he is past president. Experimental Aircraft Association (EAA) chapter 406, “Is creating BACE (Bremerton Aviation Center for Education), a place where people can come to learn hands-on skills in airplane design, construction, and maintenance. Our shop area and flight …

“The Quest for a Truly Practical Electric Touring Motor-Glider” Mike Friend is not your typical retired aircraft executive.  As Technical Director for Boeing, he oversaw “the first manned fixed wing aircraft powered by a hydrogen fuel cell/lithium ion battery powerplant that first flew back in 2008.”  He’s been associated with green energy projects since then, including work on the Boeing-supported Zunum project, a set of 10- to 50-passenger electric hybrid airliners.  On the personal front, he hopes to design and build the Spark Solo, a single-seat electric motorglider that will enable cross-country flights from his home base of Bremerton (Washington) Regional Airport. Working with Gabriel DeVault Motorgliders make a good combination with battery power.  Their clean lines enable using low power at cruise, and as this video from Gabriel DeVault shows, even a respectable takeoff and climb with power limited to 25 kilowatts (33.5 horsepower) in this instance. Normally, DeVault’s Sonex would make full use of its Zero Motorcycle motor’s …
