Although I havent spent much time around GB1s (except for drooling over them while they are on display and flying at airshows) I am always taken aback by how much larger the airplane appears to be in personparticularly, the tall, sweeping rudder that curves down to a sharp point with just enough ground clearance.

In order to be flown by a sport pilot, the resulting airplane must still meet the current regulations—1,320 pounds maximum gross weight, 120 knots max cruise speed, for example—but how it gets there is up to the builder. The rudder hardly calls attention to itself outside of having plenty of authority. Vso approach speed is 53 knots.

Another interesting model is the 172RG Cutlass RG, which features retractable landing gear and a more powerful Lycoming O-360-F1A6 engine, offering a cruise speed of 140 knots. For instance, Knots 2U offers a Cessna 172 Cowl / Body Fairing Kit that improves aerodynamics and can increase cruise speed by 3-4 mph.

The weather briefing we had reviewed a half hour earlier promised a 20-knot headwind that would require two fuel stops on the 130-mile trip from our home airport in Kennett, Missouri (KTKX), to Little Rock Air Force Base (KLRF) in Arkansas. The windsock promised that getting the little yellow bird into the air would be a white-knuckle affair.

With the F2, the rudder and vertical stabilizer are changed, with the rudder becoming a much smaller surface than before. You can sit there with full back stick, full aileron one way and full rudder the other, and its perfectly controllable. You might ask what happens with crosswind landings when you take away rudder authority.
