The first thing this morning, I went down into the basement in my bathrobe and checked the manometer. The right tank held pressure all night! So, I officially certify both tanks as able to hold fuel without leaking. Woo Hoo. I definitely feel as though I am finished with the majority of the wings now. I believe that I can reach my goal of finishing the wings by June. I will order the fuselage kit (slow build) at Sun-N-Fun.
