13. It is time to install the upper D-LOC™ Sheeting. The 3/32” balsa part W2 forms the upper D-LOC™. To install,
first key to the tabs in the spar S1, tack glue into position then wrap forward and down until the forward tabs
interlock with those in each of the R1, R2, and R3 ribs. Follow the photos below as a reference. Notice that W2
does not wrap all the way down to W1 – this is IMPORTANT – there will be a gap between the W1 and W2
sheets at the wing leading edge. Do not try and pinch W2 down to adhere to W1!
14. Next locate and install the 3/32” balsa W10 upper cap strips atop the ten (10) ribs R2. It is easiest to first tack
glue the cap strip in place atop the rib interlocking with W2. Once the glue has set you can continue to wrap
each cap strip down and back along each rib one at a time.
15. Install the 3/32” balsa wing tip cap stripping part W4 as indicated in the photo below.
