Some past builders have had issues with the trailing edge of the wing breaking glue joints and lifting up when the fabric is shrunk. To avoid this I thought it would be a good idea to reinforce those glue joints.
I started by cutting some RS-1 into trapezoid shapes using the band saw. It took longer to setup the band saw than it did to cut ~50 pieces.
Those were glue to the trailing edge on both sides of the ribs.
