I also have a CH601HD. I have never tried it on skis, I suspect that the biggest issue is the tendency of the prop in a tractor configuration to pull the nose downward on take-off. Build your skis and try them in low, firm snow conditions or lake ice. If your not happy with the performance you will have set of skis for your CH701 ready to go! My CH601HD thinks its a STOL aircraft with the Rotax 912 engine. You and I talked on the phone about this while I was at Can-Zac last month....if I remember names..getting old.
