I flew this one first and then the arrow per FT plans. The KFM wing needed a lot less reflex and seemed smoother overall and tracked better in my opinion.
My larger KFM wing was getting a bit beat up so I decided to upscale this to a 38” wingspan. Wanted it simple so the main area will be two foamboard pieces laminated with spars.
The KFM4 piece will wrap the leading edge thus making a nice smooth LE. Winglets and it’s done. Going to use a modified pod with a Park 480. Thinking 9 or 10” prop. Should be fun!
