Hello, i'm building an Hellcat 1,60 m span, and i need some advices for the wings.
I'm making foam wings, and i would like to have a plane that fly well at low speed.
What about these 2 options:
1) two differents airfoils. First one Naca 23018, zero degree incidence, and second one Naca 0016 (symmetrical) zero degree incidence
2) same airfoils Naca 23018, first one zero degree incidence, and second one washout 2 degree.
What do you think?
Thanks for your help.
