[C38] Two bladed Folding Props

[S. Orton]

Is anybody using the Martec Slip Stream folding two bladed propeller?  If so what size are you using?  This is a geared design constructed of 316 Stainless.  Compared to the Mark 3 Martec:  The con is the hub is slightly larger, with a greater profile drag.  The pro is the blades are much fuller at the outer diameter, giving a more efficient propeller.
