Kirk, it was great seeing you again as well. The Compensator is a wood kit with a foam wing and stab. My buddy Stan wanted a 60 sized old style pattern plane so he is buying it from me and I'm going to keep the Mach 1 and build it next winter. I ahve a friend who is selling off his kit, arf, and engine collection and i'm goin gover this week to see what is left. I heard there are some YS (2 & 4 cycle) engines NIB in the collection as well as a MK Joker.
