3-bladed props for OS160FX

[Bob Pastorello]

I have been using the APC 15.75 x 12 repitch (starts as a 13) on my OS 1.60's.  VERY good prop, and pulls well, without being overly-fast (the 13 pitch), yet still giving the 'hole shot' acceleration (like we need so desperately at the bottom of the new challenge maneuver - Reverse Avalanche).

It is a very efficient prop on the 1.60, turns in the the 76-7700 range on 15%, and brakes like a parachute.

    Try the stock 15-3/4 X 13 APC.
    You migh de-pitch it to a 12.

      So what 3 bladed prop would you use on an OS160FX?  

      Any reason to think a bolly carbon prop is better than an APC on this engine?
