I swapped my carbon props on my Phantom V1 with the props from a Phantom 2 and I noticed about a minute longer on video all things being the same. I tested the new props against my carbon fiber balanced props and was pretty surprised by the overall performance and stability. no jello differences between props - the new V2 seem to come balanced. Tested with similar batteries and giving the motors about 20 min cool down. So I guess I'm leaving the new design props on my Phantom v1!
