There is a notch in two of the propeller motor mounts. There are two props that have a raised line near the prop center. They go on the notched motor mounts. I am new and did the same thing. There was a YouTube video that helped me.My Tello will not take off, it just flips over. I think that I have discovered what the problem is, one of the propellers is different to the other three. I think that someone has replaced one.
I'm sure it did.
