washout or different airfoils?
Hello everybody, i'm making an Hellcat 1,60 m.
I have a question about the wing.
I'm looking for a model easy to fly at low speed.
I need an advice on these 2 options:
1) Naca 2415 (or 2417) on root, and Naca 2415 (or 2417) on tip with 2 degree washout
or
2) Naca 2415 (or 2417) on root and Naca 0016 (symmetrical) on tip
I'm oriented on the second option, i'm making foam wings, so it is easy to put 2 different airfoils.
What do you think?
Thx everybody!
