The design conditions for this prop were 2-bladed, 420rpm, 0.45m (18") 
diameter, 3.5m/s speed and thrust of 88N.  This was based on an input  
power of 350W.  JavaProp gives an efficiency of 87% using the  
MA409 foil.

Note that this is a thin prop, so it will need reinforcement for about the first 2".
