RE: LE slats and flaps-worth the effort?
With respect to LE flaps, I have two books with photos ( MIG Dynasty and Mil-Tech SU-27)of the Mig 29, and the Su 27, in take-off mode. Both aircraft-assuming the photos are labeled correctly- show LE flaps in the 'down' position. The Mig caption refers to a full flap, short take-off with what appears to be minimal elevator deflection on rotation. Another Mig photo at rotation, also with LE flap down, shows full taileron deflection, realizing that deflection can change in an instant. How does one correlate a long t/o with a model and a short t/o with full sized? Is there some other part of the equation, or configuration of the AC, that doesn't match?
