3-bladed props for OS160FX

[Dean Pappas]

Saludos Claudio,
First you need a pitch gauge, and then a monokote hot air gun. For this size prop, I actually use 2 heat guns, to warm the thick blade root. You will probably have to apply heat for 30 ~ 60 seconds with two heat guns. Warm the blade about 1-1/2" from the root, and twist the blade until it cools. You will need something to prevent burning your hands, like a block of wood that has a narrow hole in it. The blade can be restored to its original shape by warming, if and when you need several tries to achieve the dewsired pitch. It will take practice to keep from bending the blade along its length, while just twisting it.
 
Try practicing on a small, disposable, two-bladed prop!
 
Have Fun,

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?
