So for my next build, I want to do a custom/scratch plane in a basic monoplane/tractor configuration, with a floaty, big chord/ somewhat lower aspect style wing, and I want to use the simple type of under camber air foil method you'd find on FT planes like my DR. I'll be using 3ch V tails do everything on this one. I'm using it as an opportunity to work with different types of air foils besides flat plate/no airfoil and simplified KFM styles, starting with the easiest types to construct. I also want this plane to be nice and slow and floaty.
So as somebody with no real experience employing this type of air foil on custom builds, I have a few questions I'll be looking into, but in the mean time, figured somebody here on the forums would have the answers. So what I'm wondering about is:
1.) How much camber? what's the minimum/maximum degree of camber one would want, and what might be ideal amount for a plane like the one I want to build?
2.) How far back to crack the wing? With KFM1, the top layer is 40% of the wing's total chord. How far back along the wing's chord should I crack it?
3.)How should the wing be angled when mounted on the fuselage? I suppose I could look at my DR1 for a rough approximation, but this may differ with the degree of camber, so I figured I'd ask.
Thanks in advance
