I don't think it's as much a reliability issue as it is an availability issue. There hasn't been any new sheetmetal made for these in 25 years, the repair shops don't know what it is, and even the "parts pros" (mostly kids in spiffy uniforms) behind the counters think you mean a talon or vision. The only reliable work has, for a long time, been your own or someone you know, and a lot of people don't have the adaptability required to properly maintain one of these birds. I'm thoroughly grateful that I stumbled upon this great resource of both knowledge and encouragement! Every day, I look on here, see the progress that other like-minded individuals are making, and I get an itch. I can't scratch it yet, but I know that when I can, I will do a better job of it than if I tried to tackle everything on my own, unprepared.
