F550 props?

[Chalagi]

How to tell if the are upside down or right side up? They look the same either way

leading edge is the high one.

 

[Chalagi]

So you are saying that the leading edge would be going clockwise on arm #1 and ccw on arm #2

There should be a dji stamp on the top. And there will be a slight curve on them almost like it higs the air underneath

Other way around. Arm #1 ccw. Here is a pic for you. Before putting the props on, I would fire it up and make sure the motors are spinning the right direction. If they are not, just switch two wires between ESC and motors. Doesnt matter which two. Then put the props on and go have fun.

piece of tape on motor shaft helps see which way its spinning.
