I am at the point in my Lancair IV project where I need to order my prop.
I operate out of San Carlos which is 2500ft.  I plan on using a feathering
5 bladed MT prop which can also be ordered full reversing capability.  My
question is this:  Does anyone have any knowledge if such a system is
unstable using the beta range under 40 kts when the rudder is ineffective.
There is a 1.5 deg engine offset to the right.  Without direct nose wheel
steering I wonder if the reverse thrust could get a little dicey,
particularly on a wet and slick runway, which is the situation where I
would like the beta option.  I read recently where a Glasair III had
turbine installed.  Does anyone know who the owner is.  I don't believe the
GIII has direct steering so this installation would be of interest.
