Coax Prop Orientation - Am I overthinking this????

Whew... AD6 convert to XH8 almost done. Went to do the ole hold it over the head while the better half spins it up and felt like it was headed for flip o death. So heres what I'm wondering... When you invert that bottom motor do you install the prop right side up (leading edge) to the rotation equaling upside down to the motor??

Wookong says all tops spin Left (CCW) and all bottoms spin Right (CW). Motors are all spinning in the right direction. Leading edges are heading in the right direction. The props are all the same. I remember vague references to Pusher vs Puller, is there a different set of props I need to buy for the bottom motors???

Other causes could be...

Motors in the wrong port (checked a bunch but DJI screwed me resulting in multiple FW updates and ESC Calibrations). Very possible I've got a motor in the wrong slot.

Have not done the Wookong dance after FW upgrade. Wouldnt think this alone would cause Death. Instead Dance is used to dial in wander etc...

Finally,

It could also be...The booze (pomegranite vodka and ESC configing always goes well, the bloody cat or it flies just fine, the IMU just cant keep up with your stupid @$$ waving it over your head thankfully troubleshooting a coax with 8 blades spinning next to your head is probably better for humanity. Darwin tries...

Anyways... here's a pic of the blades as is currently mounted and as always ALL help keeping me from a divorce is very much appreciated!!!

You mount the props the same as you would on the top ... not bottom up.
The side with the model or in your case the size imprinted, face the sky.

And yes you need ccw and cw props so that when mounting with the leading edge up (side you can see the prop size printed on) they are spinning the right direction. Looks like you have APC 12x3.8 slow flyers so you need a set of APC LP12038SF on top and a set of LP12038SFP (counter rotating) on bottom.
