Per can't seem to leave the LeGrand project alone. He's added more wings, but they're smaller. The net effect is the same level of downforce but with even less weight.

That thing is so doggone fast....

I thought that was the whole point of a car like this? Is it ever really 'finished'?

Exactly.

So, by the time Per is done, he'll have to strap the LeGrand to the ground when he's not in it, because it'll drift away without his bodyweight to counteract its buoyancy. It'll be powered by unicorn farts and be made of unobtanium. Right?

Cool the first truly Green racecar. Oh wait, or would it be Pink racer since it's Unicorn farts?

It woould be nice if you showed us how to build such a wing with a home-made autoclave.

Per, How did you determine the spacing and angles of the wing elements? Is that info you are willing to share.

MW: Simon McBeath has a pretty good book on aerodynamics for competition cars. We're using that to determine basics (angles, overlaps and spacing) and will test variations from there.

I'm not concerned with drag at all, so it's a little easier than testing on a pure road racing car.

I know the LeGrand is back in the hands of Per's dad, but I wanted share a video shot yesterday in my LeGrand (used to be Joe's).

How do I embed the video????

Anyway, everyone needs to try driving a proper racecar!
