The eSpyder just got approved in Germany as an electric ultralight!
"The proven Flightstar airframe has received dozens of upgrades to enable it to be easily and affordably operated as an electric aircraft. The Yuneec 24KW (32hp) electric power system has been tested extensively and it utilizes mature battery technologies that are currently mass produced for the computer and electric vehicle industries. The electric power system can be fast charged in around two hours and it enables the plane to fly for up to an hour, with a thirty minute reserve still available upon landing. The ESpyder is extremely quiet (51dB), virtually vibration free, environmentally friendly, and cost effective. "
