I am new the phantom world and am trying to learn more about the accessories available for it. I have done a fair amount of research and reading on this forum regarding the different style of props, but am still left with some unanswered questions that I'm hoping I can get some help with. - What are the pros/cons of changing the prop diameter? (I've found some very long winded answers to this but was hoping for some simplistic feedback) - When I am looking to buy props, how do I tell if they are compatible with the phantom and will properly fit with the flats on the shaft? - Is there any recommendations for telling good quality props from bad quality props when I'm searching? (certain manufacturers, etc) Any links to where I can purchase recommended props would be appreciated.
