He's got a hydraulic c/s now but says he really liked the Aeromatic and want's to get it fixed and put it back on. It was laying around for a while and I don't think it was all that heavy. It had wood blades and he's going to replace them with carbon fiber. I will try to find out what it weighs (with short blades). Maybe I can talk him into letting me try it!
