I am studying the lak-12 airfoil (FX67-K-170,FX67-K-150, FX71-L-150/30, FX71-L-150/25) I found the coordinates but I needthe aerodynamic centre and the Clift, pitching moment Vs incidence distributions. LAK-12 have the same wing airfoil like Nimbus 2, DG-400, Jantar 2B, Janus, Pik-20 (FX-67-K170/150). How can I get the aerodynamic data to study this plane ?
