Guys, i saw some different types of propellers. I was thinking of the 3-blade propellers. What is the difference between 2 and 3 blades? I have the P3S and i´am often flying at lower attitudes, so i was thinking if it won´t get better thrust. Do you think i sould buy them? Thank you for your suggestions.

Where did you see them?  

This has been discussed quite a few times in various forums.  The consensus is, stick with the DJI props for best performance.  

Do you think i should buy them?
That all depends on whether you think that slapping on some cheap, unbalanced and unknown junk you find on ebay will give a better result that the props designed by DJI's propulsion engineers to match to the motors and ESCs.

I don't chance using anything but DJI props

Don't waste time on three bladed props. Dangerously bad. Risk your P3 or more. No kidding. Been there done that.  Stick to stock.

It's not a good deal of losing the drone for the sake of small ones.

Unlike regular RC use - Drones such as DJI are camera platforms and the Flight Controller is set-up to provide balanced, stable flight pattern. The DJI props are based on requirements to create a combination of reasonable power draw vs thrust / lift.
Our use of sticks alters the balance of the 4 motors to create movement up / down / side / fwd / back etc. The Flight Controller uses accelerometers, GPS and barometer to gauge the effect it has when  altering each motors thrust / lift.

OK - what does that have to do with changing props ? It means that Flight Controller will still provide that as long as props are in the range to fly as required. Whether 2 or 3 blade - makes little difference in fact. The FC will adjust the motors rpm and props thrust / lift to be as required for the manoeuvre.  The only possible change to performance could be in max speed - but if that is higher - then that also means flight time could be shorter.
You may also suffer higher power demand for a given command due to higher drag or weight of the props.

In regular RC and where the model plane is to be used in a specific style of flying - it is common to play with blade count, pitch, diameter to arrive at desired. But with these Phantoms - we are looking at overall compromise to provide stable and dependable long flights. I suggest the DJI prop may just be the props to use.

Thank you !

Thank you all guys !
