I have an FPV Twinstar where the props don't spin at exactly the same speed causing a pulsing sound and increased vibrations for the gyros and camera to have to deal with. Since I can't seem to solve this problem with the ESC, I wanted to use a little ER9X magic to do it.
I will use 2 channels for Throttle mixed together.
How do I also create a POT mix so I can adjust the speed of each motor inversely just about 10% maximum?
Thank you.

Assuming two throttle channels are in use...
I would just add another mix to each throttle channel with the source as say... P1.
Then apply a curve to each individual mix.. So rotating left, affects one throttle channel, and rotating right affects the other.

Re: Twin Motor prop sync trim
Add to one throttle channel
-10%P1 Curve (x>0)
to the other
+10%P1 Curve(x<0)
Turning P1 either side of centre will back off onbe or the other throttle channels by up to 10% (The 10% weight in the mixes).
