unfortunately these are not good quality - i had to grind 6 of 7 adapters i ordered, because in the place where the thread ends it was 0.3mm more than 5mm diameter and the prop rings (exactly 5.0mm) did not fit. also the balance is not very good :(
David, I have been using ntm 2826 1000KV motors with these adapters on my Talon Tricopter for quite a long time now. I have used the stock threaded spinner on all props. Just make sure to add a drop of medium-strength thread-lock to the spinner on the clockwise rotating props (when viewed from above the multirotor). If you use medium-strength thread lock you won't have any problems. Don't use high-strength thread lock though, or you will have trouble removing your props later on.
if you mean this motor, PRODUCT ID: D2822-141450 NO it wont work, You can modify the motor to mount behind a firewall, by changing the shaft or pushing it through so it sticks out the other side. Make a new flat spot on the shaft near the end for the set screw.
Arrived nice. should have been included in with the motor. Anyway, can't complain now.

Overall very nicely machined. However, the cross is a bit weak, compared to other sources - it bends at the inner holes quite easily. This is almost not noticeable when actually attached to the motor, but still it's a bit weaker than others.
The propeller mount fit is sometimes very snug, so you have to use the screws to actually drive it onto the motor (by hand it wont go on)
