I figured that putting the wings at an angle would be better, as wings on real aircraft are also put at a small angle and designed such that the fuselage is horizontal in cruise (to minimize drag, and maximize passenger comfort). The physics system in KSP does not seem to work that way. I guess angle of attack is simplified by measuring between flight path vector and main body axis, not separately for the wing. Also, does flying at a high AoA result in a higher drag? Or is drag simplified to a single constant that does something with air density and speed? Will try to beat the record tomorrow or so
