Perhaps the facts would help on the subject of the Suxess.

A couple of words is all it takes. Non-linear coupling. While the airplane flew brilliantly in most regimes, the F programs, with their high knife-edged performance requirements brought out the disadvantages of this fact of biplanes. Coupling on biplanes is much less linear with rudder and throttle position than on monoplanes. The idea of F3A design is to reduce pilot workload as much as possible to allow for concentration on things like geometry. Non-linear coupling creates difficulties that a pilot does not need when the object is to win. The monoplane, easier to tune, easier to fly, is simply the bigger stick at that level. His new design should present a very big stick for any competitor and is reported as being more than remarkable in the wind and turbulance resistance.
