I'm trying to gather a collection of a few (about 5 or 6 different makes/models) props for my minis and test them myself.
I was going through the new items page at hobbyking webstore and realize for the first time that Gemfan sell the exact same propeller in two different materials: CRP and ABS. With my limited knowledge in the polymeric materials area, I understood that CRP is probably "Carbon Reinforced Polymer" in this case Nylon, and ABS is the common thermoplastic that we all know.
GF 5x3 ABS Version:

A bulk of GF 5x4 ABS:

A bulk of GF 5x4 CRP:

Besides the price, I understand ABS is way more brittle and less forgiving when hitting something, it will brake easily. On the other hand, the ABS versions are probably a little lighter than the CRP.
What are your thoughts on this two different gemfan props?
Is it as simple as "ABS is rubbish, go for CRP" and thats it?
