I bought this off of a local fellow who had bought it off of someone in the intention to fly it himself but never did. It's at least 35 years old. Whoever built it did a beautiful job on everything but the radio and engine installation which was horrendous. After ripping out the engine mount, filling in several holes in the firewall, I pulled the MDS .46 that was in it and replaced it with an OS .55 AX. The radio installation was completely re-done. and several Monokote patches later and it was ready to go. It's an absolute pleasure to fly. I always wanted one of these when I was a kid but they were always out of reach financially for me. I now have a complete kit to build another some day and a 2nd laser cut short kit. I think I love building more than flying!
