Chipmunk sounds cool..Kinda strange, at least to me, about adding a shim. I have seen several other planes from them and all share several common things. Directions are all at the same level. A few headaches during the builds. But all seems forgotten when it take to the air.
Glad to here about the addition af a Ultimate. I have found a new favorite and the Ultimate 40 is it..small, easy to carry and a thrill to fly. Have fun!!
