LIBERATOR

    First flight 1989....span 63"....51oz....20 oz per sq ft....one OS10 in the tail....Gr 7 * 4 LH....rudder and elevator controls....mostly balsa....

   It's amazing, what an OS 10 will fly.

   As originally tested, it was directionally unstable. After some experimentation, this was corrected by introducing a progressive change of wing section, giving the tips more camber and a few degrees of washout.
