To windy to fly today... so what to do? I found a Wing called "The David" at this link... https://www.rcgroups.com/forums/show....php?t=1173701
It is coming along good, I decided to add the color during the build. It is covered with vinyl covering leftovers from work that we use to make temporary "N" numbers and markings for the planes. It sticks on good and is strong, I have several different colors to use. Decided on the Red and Yellow while the Elevons and the winglets will be blue. The airfoil is a KMf4 with balsa leading edges and a carbon spar in between the layers for strength. I have a cool graphic of some eyes I think I will put on it. Going to power it with my trusty GH 2408-21 and a 6x4 APC prop, not sure what battery yet. I still have to finish the Elevons yet and get the running gear installed.

Well my 20 inch "David" is done... Ready for balancing and maiden. This one is going to be a handful... It's the smallest wing I have built to date. Went together quickly. Added winglets...
