The reason for the 3 wings was to increace wing area therby making for a lower wingloading, this equals a much better climb rate. You do not want to simply increace wingspan as this reduces roll rate. Because of the rotary engine's massive gyroscopic effect it wouls not react like a normal plane, if you could master it , it was extremely agile. Just like Sopwith Camel, you used the same direction of rudder offset to turn left and right! These rotaries also dod not have a norma throttle, you had selector switches that turned off some of the spark plus thereby decreacing power. That is why they "blipped" the engine for landing. Theuns
