Sopwith Triplane

The Sopwith Triplane originally used the Ace Mini Foam Wing.  This kit includes 42 ribs for balsa wings.  Leading edge is 3/16″ balsa.  When you build the wings, make sure you tilt certain ribs in each wing panel to match the angle of the struts.

Here’s a plan you can use for the Ace Mini Foam Wing.
