Remember that wings, propeller blades, and tail surfaces are airfoil-shaped. Ice build-up on the airframe changes the airflow pattern around these airfoils. It most commonly forms on the leading edges of your aircraft, including the wings, tail, and horizontal stabilizer, as well as on the propeller blades and pitot tubes.

True, a slightly higher aspect ratio wing was desired, which in turn required a larger vertical tail and thus a little extra mass, but the size, approximately 20% larger than a Widgeon, was set. The airfoil is a Harry Riblett shape, giving modernized flow separation on the leading edge for a soft stall yet with good lift and drag performance.

Planespotters note the F2’s separate ailerons and flaps, conventional tail. For one thing, the F2s fuselage hangs from a completely new wing with two distinct airfoil shapes. An obvious discontinuity leads to a thinner airfoil inboard. Out back, theres an entirely new tail.
