RE: AMR 33% Waco YMF-5 Build
Hey TR
I have studied what Anthony has done on his tip and studied the wing tip on that other small WACO thread. I looks like I will need to modify the last three ribs on the wings. Also have to shape the wing spar where the aileron attaches. It has a curved shape on the bottom towards the top as it goes out towards the tip. It appears to curve more on the bottom than on the top. The last rib appears to have negative incidence in relation to the other ribs. Each of the last three ribs appear to have this and it increases out to the last rib. This should provide the negative angle of attack at the tip to delay the tip stall. Am I anywhere in the ball park on this?
