Okay, let's say that you have a biplane with both top and bottom wings (Clark-Y) set at zero (to the datum line). If built per instructions the tail will have 3 degrees positive incidence. When seen flying at cruise throttle, it appears to be dragging it's behind, while the full scale flys much as does the cub or the DC-3 (tail high). Would you say that it presents too much wing to the airstream?
