William,
Yes, a VP prop has noticeable slowing effect when fully fine and idling. If I
were dead stick with idling engine and looking to be short on the landing spot,
I'd run the pitch to coarse for a bit more float to try and make the spot.
In my case, I'd be able to feather the prop for even better glide performance.
In your case, you will have to do some testing on another (suitably longer)
field
to determine how to takeoff and land in your available 450 yards.
Blue skies & tailwinds,

I am wondering about the length of strip I intend to use for a mono classic (to
be converted to tailwheel). 450yards - slight uphill. The figures look marginal.
Does a variable pitch prop have any slowing affect when fully fine and idling?
