Thanks for sharing that study. Cool data and havent seen that before.

Yes shape is similar however in my short study of few CFD runs you need that similar dip also underside the get lowest drag like see on the top. You also need to scale the dip to length to get best values.

friend who does these cfd for living calculated that last model and they got Cd 0,116 on professional software. that model Lt/Ltmax is 0,315. if you put that to the onorato chart seen on that pdf study its pretty good result. again I am still not confident in the result and friend will also check can he find why difference is so big between two programs
