+1,127,812,389.Stick with DJI props. They were designed for the Phantom, tested by DJI, and known to work well.
If you could improve the performance by slapping on some cheap 3-blade props, DJI propulsion engineers would have done it for you.Seen some three blade carbon props on Ali express they say they are for phantom 3 etc not sure if they are any good etc any thoughts from out there on them
