Indeed, right you are. And they were reasonably fast, too. The addition (or reduction) of horsepower will change the cruise speed some, but will have a huge impact on the rate of climb. If I'm gonna downrate the top end speed I think I'd rather do it with prop pitch to keep the high climb rates. Just my theory but I'm hoping someone's tried it. I have my PPSEL and medical. Dear old dad elected not to renew his medical... so I'm calling him my "speed bump." :) ------------------------------------ Richard Rankin richardanddonya (at) cox (dot) net N328FT (reserved - as of today!)
