Here is my field test of the DJI Phantom 3 carbon fiber propellers. I must confess that I was impressed! They look great and I did notice a slight speed increase and a more precise hover. They weigh less than the propellers that shipped with the Phantom 3 too, so that an advantage. I purchased the ones with the yellow stripes. You can find yellow and other colors of DJI Phantom 3 carbon fiber propellers here.
