I'm "in love" with that very thick airfoil at the root of the wing. It will be right at 2 3/4 inches thick. To me the Fli has such nice lines. Well i guess it is a classic
OK back to airfoils... I know the 4 digit NACA airfoils are very popular. They might be the better choice at least for the tip airfoil and leave the 63A018 at the root. This should ensure the root stalls first but looking at the graph it might have a funny stall . This airplane designing thing is starting to get above my pay grade
OK one last question, ya right
What are some of the popular airfoils used for model aerobatic aircraft? Like I said, I want to use a very thick airfoil at the root as that is part of the character of the Fli.
