A popular mis-understanding about rotor is, CW/CCW does not mean the direction of motor rotation, as motor can rotate either clockwise or counter-clockwise, by just changing the order of input cables. So it makes no sense to identify a motor type by their spinning direction.
Instead, CW or CCW motor refers to the thread direction on motor shaft, rather than the direction of rotation, in terms of motor types. That is how you specify motor type when you order from motor vendors.
Why CW/CCW motor matters as it needs to be matched with right propeller type, i.e., push propeller and pull propeller, to generate self-locking effect.
The output thrust vector of a motor setup can be regarded as a function of motor type(CW/CCW), propeller type (push/pull) and input cable order. It is possible to have same output with different combination of inputs.
So it is very ambiguity in D800's manual that what its marked 'CW/CCW' really means. A good guess is since it looks like DJI style of motor layout, so probably the frame is specially designed for DJI flight controller, that all top four spinning ccw and cw in bottom.
PX4 uses a different motor mapping layout, and it is defined in PX4 code. So better to follow PX4 style if use PX4 compatible flight controller otherwise very confusing.
