Hello everyone. On quadcopters, compared to tricopters, one must have two propellers spinning in one direction and two in the other. Is there a counter part to this product that has windings in the other direction, so it doesn't unscrew itself when spinning it in the opposite direction? I really need help on this one! Thanks a lot!

No there isn't, not for NTM anyway. There really is no need for it as long as you tighten them up firmly. Finger tight is not enough.

It's best to use M5 lock nuts instead of those spinners as the nuts won't loosen with angular acceleration and vibrations.

Actually the force when starting a propeller in the normal clockwise direction would cause the unscrew problem you refer to also on the tricopters. The counterclockwise setup would tighten the nut. Anyway, the spinners for these motors have a perfect hole in which you can put a generic turnigy hex tool (make sure to not just put the tip in as it will break off) and hold the propeller firmly while tightening the nut. A little thread-lock could be used if you're worried.

is it necessary to get the short shaft NTM motors?
 Senator315 2037 points
No as the prop adaptor sits on the opposite side of the shaft.

Can i use this spinner to ntm 2826 short shaft and ntm 2826 with shaft?
 Senator315 2037 points
Yes, it fits both those motors. Get the short shaft motors if you haven't already got them.

The cone in this kit is absolute ****. knocks the balance out of a motor. Switch to M4 nut. Aluminum if you can find it.

Same for me

I should of said M5 nut. Anyway I ended up pulling all my NTM motors off and replaced them with Multistar and a fixed 6mm shaft on the motor can. I have not looked back. The motors are good, the mount is ****

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)

Perfect fit to the NTM28-26A motor. This part actually should have been included in with the motor. I don't mind increase the price of motor for this parts.
