Default RE: A matter of thrust
PS,
Check out Gylesaero for a nice calculator that lets you see how thrust (and power demand) deminishes with airspeed

Power demand is a bit misleading, because at very low lift coefficient, when plane speed exceeds pitch speed, the flatbottom foils tend to have a very lousy lift/drag ratio.
