Rookie mistake. Picked up 4-props on Amazon that are self tightening carbon fiber. They weren't bad but they did chip on a fall. I'm replacing with DJI Props (self tightening) but of course I can't get the old ones off. See shot below. If you've had this problem how did you get around it? I have one prop off and can't get the other three off. I'm worried about effecting my anti-gravity motors. I did try the tool that the phantom came with. Even on the motor that doesn't have a prop on it I can't see how this will help. I appreciate any and all suggestions. Thanks in advance!
