lIKE THE TITLE SAYS, THE TWO BLACK FOTS MOTORS FEELS SNAPPIER WHEN I TURN THEM BY HAND, NO FRICTION, UT I CAN FEEL THEIR MAGNETS AS IF THEY WERE STRONGER.  DRONE FLIES PERFECTLY,  BUT THIS IS PERHAPS THESE TWO MOTORS  ARE OPPOSED TO EACHOTHERS SO ANY DIFFERENCE IN TORQUE GETS COMPENSATED BY THE ONE AT THE OTHER END. BUT STILL, I WONDER WHY THESE TWO FEEL SNAPPIER. ? PLEASE HELP,, DOES YOURS FEEL  THE SAME?

First turn OFF the CAPS. Now are your turning the props in the same direction of spin? One set turns CW and the other set CCW.

Regardless of which way I turn them, the two motors with black dots feel definitely as if their magnets were stronger. This is something I always noticed from day one. They do not overheat, and temperature has always been pretty much the same for all 4 motors after each flight.

It makes no difference, the motor speed is set by the respective ESC.
Torque factors in more than motor rpm on the CW turning motors.  
I'm right handed and turning door knobs clockwise is always easier to me.

Thanks,, I am still concerned a little bit even though after 72 flights never had a problem.. but I do wonder why the magnetism in these two is stronger.... quality control fail?  that would make sense since they are soo damn cheap to start with

They may have been manufactured in different factories, perhaps different production methods. I would say if you've got 72 flights under your belt then nothing to worry about. If it does fail under warranty then I would be 99.99% certain that DJI would repair free.
