Just sent you an email Mike. I was able to get in touch with Mitch when I needed some support last month, but it did take a lot of patience. And at least as of then the website was still up, but I will say even when it was up it was obviously not being maintained with lots of dead links, missing manuals, etc.
With regard to the Corsair wing fold, could you retrofit some more easily available actuators to it? I know guys use some Actuonix servos for swinging the wings on F-14s, maybe they make something up to the task of the Corsair folding mechanism. Looking at CARF's website, I guess their preferred method is hydraulics.
