Ha, I'm lucky if I have a plane left after one season. I built my first biplane in late 80s. I built the BUSA Phaeton II and still have it today. I had 2 mishaps with it and after setting for over 10 years I just went through, removed the old covering, fix any trouble spots I had and recovered it in Monokote. As soon as I get some more flight time in I'll get it back in the air. She is my oldest plane still in flying condition.
