Print the 60 size Super Kaos plan from RCM at 75% size, and build the plane right on the plan. Use 1/16″ wing sheeting, and 1/4″ x 1/4″ hard spars. Leading edge is 1/4″ thick. Trailing edge is 1/4″ square. Place the leading edge stick flat against the nose of the ribs.
Kit comes with shear webs. Study them carefully and be aware that the plan calls for the wing to have a dihedral angle on the bottom only. Tip to tip, the wing is flat on top. The shear webs will set the dihedral and the rib spacing where it belongs.
Fuselage top stringer is 1/4″ x 1/4″. Tail dragger only.
