Sorry if this has been discussed already. I've searched the board many times and I'm having a hard time finding a definitive guide to possible propeller upgrades for the Phantom 1. I'm currently running stock 8" props on my Phantom 1 and though it flies fine, I don't feel it performs the way it should. Over the last few months my copter has put on a little weight (gimbal, gopro, extended length landing arms, prop guards). The flying characteristics have changed somewhat and from what I've read, moving up to 9" blades helps with thrust and overall movement. I've read good and bad stories about prop upgrades. I'm not on any type of budget. I don't want to save a few bucks and buy a cheap knockoff setup. I want something good that will improve my flying time and overall flying experience. It would be great to get a few minutes of extra flying time as well. So, in everyone's opinion what would be a proper 9" propeller upgrade for the Phantom 1? My Phantom uses the nuts to lock down the props. I don't have self tightening ones. Thanks!
