Redline said:Hate to say it but you get what you pay for! Stop trying to save a few bucks, it like buying a Corvette and buying cheap tires and wondering why it handles like crap! Let's face it guys these quads are not cheap as far as quads go and DJI did there homework when making them just go right to DJI when it comes to a rotating part. If you think they cost a lot take a look at TREX-700 I have over $5000 into just one of them if I put a cheap blade on that bird some one would get killed.balanced props are important
Don't take chances on props,not worth loosing your Phantom and your Gopro!
+1 from me
