Yes indeed BB the YS110 is the engine of choice at the basin!

Maybe this message should be in the basin thread, but I did some calculations on the theoretical top speed with a 10 inch pitch prop (the 12x10 most commonly used), assuming no slippage (impossible, but it does give a theoretical maximum possible top speed).

It goes like this, assuming the prop pulls the plane forward the 10 inches provided per revolution by the pitch..

10 inch x 11500 RPM (about the norm for a 110 turning a 12x10) = 115000 inches per minute

=11500/63360 miles per minute = 1.81 miles per minute

=1.81 x 60 mph = 108 mph.

How can that be? I'm sure we've clocked one of the warbirds at the basin at over 130 mph.

Where did I go wrong?
