Maybe its the lube or lack of lube they are using but I cleaned them out and repacked them with synthetic oil and they improve dramatically. But who wants to have to do this to brand new motors. I've had to replace the bearings in one where the top seal completely came off, wont buy these again needless to say.

I've had nothing but problems with these motors. The bearing's give off easily. I ended up buying bearings too.
They just don't hold up !!

Can anyone tell me weight for RSII 2207 2550KV?

I found them on Ali-Express but, it seem that all the sellers posted RSII 2306 weight on their RSII 2207 sales page.

I have a theory that they were being bent by tree bark scraped up underneath the motor bell, not really the motors fault.

Is emax going to do a "popo pro" version of the motor ? I cannot be bothered with prop nuts anymore.

Hi,
I get set of 2CW and 2CCW 2306 1900KV motors from alix. It seems like all 4 motors have same thread (as CW) despite on the box there's clearly marked CW and CCW. Is that normal or should I claim that?

You are lucky to receive both CW motors, RSII have only CW thread. If you would have received CCW that would probably mean it is fake Honestly, never saw RSII motor with CCW thread, despite some listings saying it should be CCW.
Anyone has CCW Emax RSII ?

Glad I'm not crazy my bearings went on the 2207 motor and I never even crashed. I was hesitating replacing these motors with something else, after coming to this thread it's an easy decision.
