RE: Building a Dynaflite Super Decathlon
The instructions to some of the details are not so clearly marked. I had to search the parts of my box for several minutes before I found the "rib doubler" they where instructing me to find. The rib doubler is glued to the inboard part of the wing tip attaching to rib W4. Here is the location of that rib doubler and what die cut section it's from.
From there I can start on the ailerons.
