Tonight I test fit the I-strut doublers in preparation to glue three sides like I did on the lower wings. I think mixed up glue and glued all 4 of the I-strut doublers. I left the tops off so I could transfer the I-strut holes throught the 1/4 wood.
After I glued all the doublers I had some spare time so I started playing with the location of the tips bows. After some tweeking I was able to get all the geometry correct and I marked both tip bows. Later I will need to cut and taper the spars down to meet the tip bows but that is another day.
