Carl , a really good G62 will fly that plane pretty well if its a lighter build. I was at a warbird fly in Owatonna Mn. one year and the guy had really done a lot of prop testing he was getting the most out of it he could.. I swear he had to be doing 80-90 mph with the G62 in it. Maybe it was just a freaky good G62? But it went pretty fast for that big of an airframe.
