so I don't know how to do a poll or I would have done this that way, but I'm curious to see what the majority of people are using. I recently swapped to the carbon fiber 9450's from the ones that came factory. I would def. say they are stiffer, but seems my bird has more movement while hovering, and maybe a tad more prop noise which isn't really a bother. Interested to hear those who have more flight time experiences and what u all prefer and why?  I thought they might help with the thin air at high elevation. I'm near Tahoe in northern Cali. I can't tell much of a difference.
   Happy flying!!

I purchased the same and they are thinner than the stock, more stiff and weigh 1 gram less per prop. I can hardly see any performance differences with the exception that the P3 is a little more "snappy" in movements...

Five different Phantoms, all sporting the regular ol' 9450's.

I have the carbon props - didnt see any difference from the stock ones

I have the carbon ones as well.  I dont really notice much of a difference either.  Perhaps the phantom will have a better chance of winning in a bird attack with them.  

that's funny, my CFR props definitely seem more quiet than the composite props

is this better then this?

the price is 200% more then the original propps is it worth it?

What's the difference between the stock 9450's that come stock and the 9450 composite? I am guessing the Carbon Fiber 9450 is a stronger prop overall?

so is it worth?

I use the white plastic stock one for 3 reasons:

1 - they can cause less injuries if they hit someone.
2 - they can break easily and don't cause damage to the motor.
3 - they are cheaper .
