I have a set of Graham Lee 7/8 Nieuport plans that has been following me around for about the last 30 years. Don't know if I'll ever get started on it, but after watching a video on electric power for ultralights it got me thinking...It doesn't look like the motor with the batteries would weigh much more than a two stroke Rotax, but the price would be about double. Not a cross county machine by any stretch of the imagination, but should give one about 45 minutes of bugs on your teeth fun...any thoughts?
