REFLECTOR: Catto Prop

[KeithHallsten]

Dave,

How goes the prop testing?  Did you get a chance to get some data with the
80" pitch prop on your plane?  Craig advises that the 76" pitch prop he
originally made for you will probably be an excellent fit for my fixed-gear
XL.  I'm still months away from being ready to install the prop, but I'm
curious about your latest findings!
