Hi folks, I've been evaluating my next project and I'm thinking of building a Piper PA-18 Super Cub.
The trick is that basically I want a plane that is quite aerobatic but also stable on landings, for this I want to make some modifications such as increasing the flaps and ailerons to 1/3 of the wing chord, configure a mix to use the flaps as ailerons to get a more agile performance, and finally change the wing profile from a flat bottom for a semi symmetrical profile to get better performance in inverted flight.
Now, what worries me is that although I have an idea of how to make the modification, I am not 100% sure.
Of course I want to keep the same chord and wingspan, but my doubt is what would be the incidence of the new airfoil. My first bet would be to keep the chord line or angle of attack the same, but I don't know how correct this is. All this is assuming that I will keep the elevator and engine with the original incidence of the plane.
Here is the plan https://aerofred.com/details.php?image_id=98162
I will resize it to 1500mm wingspan
Any ideas?
