Yes...but it is a working electricity creating wing...not an aeroplane wing.

IIRC the negative Cm means that it will pitch up into a stall. Which means a H-tail is needed to counteract the Cm of the wing.Cm...what about it ?

You already have a very high AoA of 18 degrees. With out seeing the polar plots it is hard to say what it is doing.

Normal convention is negative Cm is a nose down moment. At 18+ degrees AoA I’m guessing he’s well past the linear increase in Cl and XFLR is throwing out weird results.IIRC the negative Cm means that it will pitch up into a stall. Which means a H-tail is needed to counteract the Cm of the wing.

And as Topaz said, inviscid isn't that good.

*insert your own definition of reasonable here.

Yes latter is such.

Thanks guys !

There’s a series of YouTube videos that I’m working through to see if it seems worth the price.

Not really a version of XFLR5.

There are several related programs, all from the same developer. My conjecture is that they used the same basic algorithms to solve the fluid dynamics, but each is tailored for different purposes.
