Using flaps for take off on swept wing aircraft like the F86 is very helpful. The full scale F86 used 50% flap for take off. I found that 50% flap reduces the extreme angle of attack that is normally needed at rotation to get the swept wing to fly at lift off. They have the same impact on landing, they reduce the high angle of attack needed to keep the swept wing flying at landing speed. Of course with full flap on landing more drag is added to slow the Sabre on the glide slope.
