No not even close to a spitfire.

They said the motor makes 100+ hp and weighs 30 lbs together with the controller. Holy crap, I want that kind of power density in an ebike!

Though the Spitfire isn't the only plane to use the elliptical tip planform, this one is similar enough that there is a strong resemblance.

And yes, that Siemans motor is incredible... 5 to 1 thrust to weight ratio. It's picturing the electric Edge 300 that just set a time to climb record.

I guess you are refering to the Extra 330LE ? That set the clime record.
Which is a much bigger craft powered by the bigger Siemens 260d electric motor with 260kW (and 50kg)
The pictured Hamilton Aero is a small aerobatic kit plane.

Yes, my mistake, I meant the Extra. And this one has the 100kw Siemens in it.

My favourite motor is EMRAX 268 (230kW, 500Nm, 20kg) but i´s more or less a direct drive cause of less turns around 5500 (no load).
They also have the new 348 model (up to 400kW, 1000Nm, 40kg) but less turns and also 5 digit price!
And I found Siemens:
http://w3.siemens.com/topics/global/en/ ... -ecar.aspx
Check out the turns!
Price: I really don´t know!
- Fastest speed record 200,49 kph on flat after 740m (175V, 400A)
- Fastest 1/4 mile @ 157,12 kph on flat and 14.468 sec (146V, 600A)

14/34kW QS-Motor 273 80H 7T winding (560A and 1740 turns @ 144V) @ 169kg GSXR 1000 K2

Wow....retractable gear and everything! Yeah, SPITFIRE is the first thing that popped into my head when I saw that. Lot's of aero advantages to a planform like that I understand, but a royal PITA to build, and a bigger parts count, compared to a constant chord wing.

What I'd really like to see.....is a aero drive like my Prius has. Hell, I put 1300 hours on a Subaru powered airplane, maybe I ought to yank the Prius driveline out and try it! Point being, a hybrid rather then a pure electric is what I can almost see in my future, a smaller ICE but when helped out by the battery still plenty of thrust, combined with super economical cruise. Regen during descents would be a really cool feature! No free lunch though, if that ever happened, it'd have to impact the glide ratio, as in a windmilling prop has a lot of drag, way more then a stopped one. When I dead stick ridge soar my plane, the increase in glide from an idling prop to a stopped one is dramatic. https://www.youtube.com/watch?v=8J9v433C0nM
