The 301 aerofoil is a lot thinner & designed for flaps so very different.

I have spoken to Christian Streifeneder regarding turbulators, he has pointed out that there may be a case for putting them on the top surface of the wing, but then it would be difficult to wash the wings. He's not convinced they are effective on the underside.

By the way, there is no H in 201 (regardless of what Wikipedia says) - the H in H301 denotes Hutter who was involved in it's design, but the 201 did not.

Cheers,
Nick.
