Just in case someone comes across this thread and is left wondering which is "right", here is the text from the 07-Feb-2014 version 1.10 of the s800 EVO User Manual:
"
Assemble the Vibration Absorber of MotorsThe soft gasket is apart of the Vibration Absorber and it has a thick end and a thin end, it’s important to assemble the soft gaskets in correct approach adhere to the diagram below.
Propeller CCW: the thick ends of the gaskets (A) are upwards, the thick ends of the gaskets (B) are downwards.
Propeller CW: the thick ends of the gaskets (C) are downwards, the thick ends of the gaskets (D) are upwards."
This text is accompanied by a diagram illustrating the proper orientation of the gaskets that makes clear that this specified approach (as viewed from the motor end of the arm) will result in:
Clockwise rotation motors being canted slightly to the Right, and
Counter-Clockwise rotation motors being canted slightly to the Left.
Of course, one is free to follow or ignore DJI's instruction, but it is pretty ridiculous to assert that this differential orientation of the motors is not 'what the engineer wanted'. I received an early model s800 EVO without the 'Vibration Absorbing' assemblies. In the early models, the motor canting was in the same directions, but was accomplished with rigid shims on the appropriate sides of the motors to produce the same effect. This was the same approach used in the original s800. Subsequently the Vibration Absorbing assemblies were developed and the asymmetrical gaskets were oriented appropriately to produce the desired slight differential canting of the CW vs. CCW motors.

The whole idea of tilting the motors is silly. The grommets are not holding up when installed upside down as widely reported. One user said they saw failure within 2 hours of flight time. I have re-installed all of my grommets with the large end up as they were designed to be installed. The manual and the whole idea of tilting the motors is an after thought. I flew mine for 30 minutes today without the tilt and it flies as it should with plenty of yaw authority. I believe this is yet another example of a half-baked ideas that are not tested or though out before being released to the public. If an engineer wanted the motors tilted, they would have designed it into the arm.
I really like my DJI equipment and prefer DJI products when building but sometimes they do these stupid things that just makes things worse. Still waiting for them to repair the damage they did to the H3-2D gimbal with the last software release, that was a total brain fart on their part.
