18-1: Built wing cradle before beginning Wing Tank construction. Basic design borrowed from some of the other builders http://lrosen.nerv10.com/Construct/WingStand/index.html
Used different center bracing that seemed more straight forward. Used the two 2x6's like in some of the previous models. 2x4s probably would have worked ok as the 2x6s tended to cause some warping in the cradle without load on it. Hard to find 2x6s without much twist.
