Speed record set for all-electric airplane – 204.4 mph

Chip Yates does not like sitting still. Just a day after piloting his electric-powered Long EZ airplane to over 200 miles per hour – making him the fastest electric-airplane pilot in the world – he had to disassemble the airplane, pack it up and drive 2,000 miles east to Oshkosh, Wisconsin. Here at Airventure, Yates continues to be busy answering questions about his record-setting run. And perhaps one of the more surprising answers is that Yates is a not a veteran test pilot. He just got his license in June and has about 58 hours of experience, including the record-setting run last week.

When the electric vehicle pioneer bought the used airplane it had a 118 horsepower, four-cylinder gasoline-powered engine that is fairly standard for a Long EZ. Over the course of several months Yates and his team pulled the four-cylinder engine out of the Long EZ. They then pulled the 193 kW (258 hp), liquid cooled electric motor out of his record setting battery powered motorcycle and mounted it to the back of the Long EZ.

With the very well used (Yates calls it “abused”) lithium polymer battery back from the motorcycle in the back seat, the Long EZ was being prepared as a test bed for some of the technologies Yates needs to develop for his transatlantic flight. But after setting speed records for an electric motorcycle, first up for the Long EZ was a speed run.

The dawn of electric airplanes – first all-electric transatlantic flight coming in 2014

Electric vehicle pioneer Chip Yates is upping the ante in the world of electric airplanes. Today, the world-record holder for electric motorcycles announced plans for an all-electric recreation of Charles Lindbergh’s famous trans-Atlantic flight in 1927. And Yates isn’t content with just retracing the path across the Atlantic. He’s betting that like Lindbergh’s, his airplane will fly non-stop to Paris. Yates plans on flying at least as fast as Lindbergh’s Spirit of St. Louis, and for added challenge and recreation authenticity, he’ll fly relatively low to avoid getting an extra push from the jet stream.

Yates is currently preparing an existing airplane to serve as a test bed for his electrical propulsion system. The airplane is a modified Long-EZ, an efficient design from the desk of Burt Rutan. The first flight of the electric test bed is expected in July. And because it’s a Chip Yates project, he plans to set speed and altitude records with the airplane while testing.

“You could fly this route today in an unmanned solar craft at 80,000 feet being blown over there by the Jetstream, or in something incredibly slow, or in a balloon,” Yates said in a press release, “but that doesn’t get our society any closer to realizing long-range, legitimate payload, electric flight capabilities that everybody can actually benefit from.”
