Originally built around 1990 and flown probably hundreds of times by me, I was forced to rebuild it a couple of years ago when I discovered some critical airframe failures. I repaired the airframe and used new covering, new hardware, new hinges, a new fuel system and tank, new Robart landing gear, new Stan's Fiber Tech cowl, new Lexan windows and a new Spektrum DX7 radio to make it better than new. The OS Gemini 1.20 twin still runs perfectly. It should be good for another 20 years.
