People have tried them. Most don't work well and they might cause your Phantom to crash. It's best to use OEM DJI props.

Lots of previous threads. Have you thought of searching the site?
Adding blades does not improve performance and reduces efficiency.
Adding blades is a method to reduce disc diameter for design considerations such as ground or fuselage clearance or to make use of increased power where increasing blade length is otherwise impossible or impractical.

Well I am sure msinger will reply, but props are one of the single source of failure, you lose a prop, and you are down, same with batteries, so..
I do not take a risk with these items. I also think a huge amount of research has gone into the OEM stuff, so for props, I stay with DJI ,OEM.
Thanks for the quick reply but I have a P4P+, I was not the original poster!!! That being said I will look at that link, again thank you!!

The size and number, 2,3,4,5,6, of the blades has to be matched to the engine power of torque. The blades can only be so long before they go sonic(outer tips) and loose lift instead of making it. As the engines produced more power the props could only get so long and then increase in number.I.E. If it has two propellers stay with two, the pitch and size of is matched to the motor.
I use carbon fiber dual blade props and my movements are exaggerated.
Exaggerated i.e
quicker movements left and right
Faster speeds (47MPH vs +/-53MPH)
The blades are a tad bit heavier but technically "lighter and faster" for its size.
I would suggest that if your bird comes with 3 blades stay with 3 blades... If it comes with 2 blades, use 2 blades, etc, etc, etc...

Something can’t be heavier yet lighter and faster, we don’t have the technology yet.
Which props are you running? Are they genuine CF woven Matt/resins Ir the FAUX CF offerings that seem to proliferate. eBay and Chinese sellers?
Whatever the aftermarket props are simple fact is that the max horizontal speed of your phantom is governed by tilt angle which is limited by the flight controller. To the extent the aftermarket props were producing greater thrust the flight controller would simply feed less power into the motors.
Reality is your aftermarket props are inferior to OEM. Below is actual thrust measurements of DJI OEM vs aftermarket 9450 style props on a test rig at various static RMP intervals.
Ultimaxx props...
The blade is a little bit more..... Bent? Sloped?
Anyhow, the blades are full carbon.
If you look really close you can see the weaves and the resin coat (some areas are not super smooth like plastic looks like)
I've laid CF before, it's the real deal...
Also when you touch the blades together it definitely makes a non-plastic "tink" sound.
I guess I'll need to record my screen showing the faster side to side speeds and elevation speeds..
I don't use fleabay for anything.
I meant the blades are heavier than OEM but for the size they are (material wise) it's lighter than OEM. If OEM was that thick it would be heavier... Hope that helps
Because it's carbon fiber!
(yeah, just a little sarcasm as it seems people always think because it's CF that it's better... despite all of the testing showing it does not make a Phantom fly any better).
Ok, gotcha- re the weight.....
Would be very interested to see any evidence of increased sustained flight speed.

Normally you'd expect that the flight controller won't allow the Phantom to go faster with non-standard props.
Do you have any testing data to show that isn't simply riding the wind?
Like a flight record showing a 500 metre run in both directions?
