EAA Lightplaneworld has an article this week regarding electric aircraft.

Technological advances in electric power are being driven by forces in the automobile industry. New designs of engines and batteries that result from these developments will trickle down to the world of aviation. ThinGap LLC has produced a 25.6-pound electric ring motor said to be capable of producing an amazing 163 hp. The ring motor is 14 inches in diameter and only 3.5 inches thick.
Finally, if you’re a simple grassroots ultralight builder, the near future can be glimpsed in the existing technology already available for the world of giant radio-controlled models. How about a 21-hp motor weighing only 6 pounds that costs $300? Even at half their rated power, two of these Turnigy CA120-70 brushless motors should be able to fly an ultralight. Caution is advised, though, as their reliability for manned flight is unproven.
