The wing area is 1925 sq in., weight should be about 26 Lbs with a 100cc class twin. As for the the servo's, I would go with four 5945's for the ailerons, not so much for the torque but having two per wing helps reduce the risk of flutter (big surface). The Three rudder servo's though is overkill. One 240+ or two 150+ is plenty(one 5955 would be great). I'm using 5945's on the ailerons and elevator a JR 8611 on the rudder, all on 6 volt. I may add a second 8611 on the rudder but I'm going to try it first.
