Nony--
Good point. I hadn't thought of the main gear _vs_ the props. The FK has decent tail area already and doesn't need to be increased. My original FK is a test bed for STOL enhancements and one of the early modifications was to increase the rudder and elevator areas, keeping the fin and stab areas the same.
Good comments, Wm. No questions as of right now.
Since I am increasing the "dry weight" and the payload of this FK, I am toying with the idea of increasing the wingspan (and wing area). From 80" wingspan (1280 in^2) to 100" ws (1600 in^2) or 120" ws (1920 in^2). With a 3-piece wing, transport of even the 10' wing will not be a problem. Of course, increased weight and wingspan will require larger engines...
Never ends, no? This isn't the first project I've had get into a "snowball mode"...
