    I bought a case of these motors, I really didn't need a whole case but the price was right and having a spar when you need it is better than waiting for the mail. Not 1 of my F450 motors have given me any trouble as of yet. But just like everything from China its only a matter of time

    "just like everything from China it's just a matter of time"......
    I would say today that some things from China may fail in time just like items from any other country. But since China is a signficant distance..... it is good to stock up.

    I would really like to try the DJI motors but can you swap off the prop adapter or are you stuff with using keyed props?

    Thanks.

    I use the Grauper 9 inch props and just reamed out the center hole of the props to accomodate the OD of the keyed slot.
    Proper centering will occur once the washer and nut are tightened down on the prop but don't go oversize on the reaming.

    How many motors were in the case, and can you share where you got them and pricing?

    Does anyone know off hand how many poles the DJI 2212-920 motors have, I'm trying to calibrate my RPM sensor.
