David- I have to echo what John said. Its guys like you that have accumulated hundreds of hours on the Helicycle that convinced me to build my own, and hopefully continue on such success stories. So far, knocking on wood, my maintenance on my whole Helicycle is less time than I spent JUST on my pre-rotator on my SparrowHawk, and not counting the cooling system, engine, and other work I did on it.
You are putting on more hours than anyone I know....and in a helicopter at that. Way to go.....and many more hours to you.
