There has been some hype about the 9450 props available, does anyone have any further information on the difference between the stock 9443 props and these new upgrades.

I understand it is stated that if you have a load bearing unit, 9450 are better and flight time could be increased, any experiences in this?

Im currently running on 9443 and have used 8045 props on my Phantom vision +

There are many aftermarket props including the folding tri blades,  any info is worthwhile for future users...

I just ordered a set (9450). I have a friend who has been using them and likes them. i compared them with a stock blade and they have a slightly different airfoil profile and are a bit stiffer. if you go with these be sure to put stock blades away somewhere as you don't want to mix them up with the new ones, very difficult to differentiate the two and mismatched blades will cause erratic flight behavior. I should have mine today and will post results unless someone else chimes in.
