When I activate CUT, Aux2 still works and in fact it goes all the way to +100 on one mix and on the other, I can't get it off the middle no matter how I mess with the rates. Also, is step 5 a typo? You say ON>AX2. Should that be THR>AX2?

Just out of curiosity I imported my iX20 Twin Otter setup, with differential thrust and throttle cut on a 2 way switch (H), into an iX14. It worked, BUT when I tried to set up the exact same assignments and mixes from scratch on the iX14, it didn't work. Must be something in the ISPM file from the 20 that the 14 can use, but can't create.

From a Spektrum engineer, this is the accepted way of doing it on a DX9. I presume it works on an NX (I have no way of testig). It sets the second throttle channel to AX1:
First you need to go to Channel Assign and set AUX1 input to INH.
Mix THR > AX1 at 100/100%. Set "Trim" to ACT so throttle trim is copied over. Set the switch so this mix is active when the throttle cut is inactive. When the throttle cut is active, this channel will now jump to the center.
To fix that position, mix ON > AX1 using the same switch but in the opposite state. Adjust the right "Rate" until the output shows the same position as the throttle in the cut mode.
You now have two throttle channels that honor Throttle Cut together. Note that ThrCut position only affects the THRO port. You need use the ON>AX1 mix to change the other throttle cut output.
Now you can do your differential throttle by having RUD > AX1 and RUD > THR as you already understand.

IT WORKS! "ON" is almost to the end of the list, 2nd from end. Didn't even have to play with rates to get the mid throttle down to -100. It was never there. I need to be more patient when trying to find something when scrolling.
That 3-pos switch thing came from a guy on YouTube (Kallend's link) named "Putzy Tart". He said he was working on something a lot simpler. I've been waiting. I'm not going to tell him you beat him to it.

Congrats on getting it!

I've just programmed your method into my Canadair. On monitor, it works. I'll need to power up the plane to make sure I don't need to reverse something. At the time the Widgen first came out, nobody in Canada sold it and to ship it from a seller in the US cost almost as much as the plane was worth. I gave up on it.

EDIT: was mistaken
Curious that only the DX20 and iX20 have built-in multi engine aircraft types. I would have thought a 10 or 14 channel TX would have been an appropriate choice for a multi without requiring heroic programming..
