Now that have have better cooling, I am able to use more power and need a bigger prop.  I installed a Catto 3-blade with more pitch and really loved it.

My old prop, seen in these pictures was meant for a normally aspirated 13B turning left handed (RD-1A and RD-1B). 
It is 68"x74" Aymar Demuth wood and served me well for 200 hrs. 

If you are like me you can use this as a cheap starter prop to get performance data that you will want before you get a custom prop built.

$700 firm INCLUDES Shipping and the spinner seen in the picture (now in gray primer).
