3)wing loading should be low - i build light but this time will put a big motor and big battery. its go 60 inch by 12 inch chord without including ailerons which is about 5 square feet. auw expected will be 5 to 6 lbs.
4) thick wing naca 0018
hows my stall characteristics looking?
The NACA 0018 is a symmetrical airfoil, not semi. Any NACA four digit airfoil who's number starts '0' has zero camber, which means symmetrical.
18% is a bit thick thick for models, it will fly but it will be very draggy.
