Send me your email in a PM and I can give you one for speed given to me by Will Robison here. It actually helps you select a prop by given rpm and approximate speed from it etc.

several months ago I found a forum in rcuniverse that had a web site to down load a calulator to find wing loading,speed,thrust,horse power I saved it, but my computer crashed and I lost it. Does any one know where I can find this forum to down load again? This time I will put it in my backup program. THANKS
