Good Luck! I had that kit in the late 70's or early 80's. I looked through my old stuff and couldn't find anything for that kit. It is a good flyer but I had a very difficult time locating my radio and linkages inside. I used a ST 35 or 40 engine. I also had some problems getting my fuel tank and engine lined up and ended up installing the engine inverted. Mine was very light. I used the old Solar Film for covering.
