Now I put the copter back together and it wont fly.
The motors and prop spin fast and have power.
The air from the props is blowing upwards and is keeping the copter on the ground.
I did notice that the props will tighten on to the rotor, but when I accelerate the props with the controller, 1 or 2 of the props seem to unscrew from the rotor.
I think I may have installed the motors in the wrong orientation and the threads on the motors are wrong, so the blades become unscrewed...
How can I reverse this to make it lift, should I reorient the motors again?
I am confused.
I saw some video on youtube that I have linked below.
They have the same issue, but they installed the motors in the wrong orientation because the top shell of the phantom was put on in the wrong direction.
My top shell is in the correct direction. Picture attached.
Sounds like you put the props on wrong. Black on black silver on silver. When you put the motor on did you check to see if the orientation of direction is correct.
But sounds like props not installed correctly.
I have come to the conclusion that the motors are oriented wrong.
You can here the rattling of the prop unscrewed and resting on thop of the spinning rotor.
Notice how the prop unscrews when I accelerate, but then screws itself back on after I stop.
I think I need to reorient each motor to solve this.
There's no way to screw the props on wrong.
They either tighten on the shaft or they don't.
I can't tell from the video if all of your props are unscrewing...
What you've done is install the CW motors in the CCW positions, and vice versa.
-or-
You've got the motors positioned properly, but wired backwards.
Look at your Phantom shell where the motor directions are molded in for reference.
#1 & #3 = CCW
#2 & #4 = CW
Mount them and wire them accordingly...

I know I'm a noob for saying this but I was literally having the same problem and your comment was the most informative and helpful thing I've read all day. IF ONLY DJI PUT THAT IN THEIR DOCUMENTATION!!! grrr... Thank you! I'm flying again and still have some daylight left to play, so the whole day wasn't a complete loss!

Except he was wrong, the props were fine, but the motors had been installed in the wrong positions.

Maybe in your case he was wrong -- in my case the props were on the wrong motors. If the documentation had said it I would have known it without reading it on a random forum post. But as for your wiring, good luck! That's delicate work!
