Oh, and TFF.... I am well aware of the safety margins.... and yes, our Co. Airport is only about 11 miles away if I were to need it due to non-STOL conditions. Non-STOLconfig will be very close to normal 350-450 ft take off and landing rolls and stall for the Biwing I'm considering.

Truthfully only a few will lend itself to the high STOL angle of attack due to flow interferences from the bottom wing... needs a good bit of setback on the lower wing. In addition there are other mods needed to the fuselage for ground clearance at that angle as well as thrust vectors to consider.

I've given enough secrets away now....
