Ed,

 you need to use an ORIG mix rather than a normal mix. When you setup the
mix choose the one that says  #thr as the master....The # sign denotes that 
you want it to
work off the stick and ignore the trim levers.  Origin mixing is what is
called on the 10X. The 9303 manual explains it but its a tough idea to get a
hold of. The throttle curve should have nothing to do with it. In fact the
throttle curve will still work and not affect the downline mix doing it this
way.

Origin mixing means go to the origin of the function and use its control
(this case the stick) to apply the mix. Otherwise your ATV values will
change the mix, and it will be dependant on any throttle curves or the
likes. Origin mixing can be very valuable. It can create mixes and
conditions that activate at certain spots on a stick, or it can totally
eliminate the rates and ATVs associated with the channel you are using as
the master and the slave only reacts based on the stick position on not the
D/R or ATV value setup on that given channel. Also trim changes will not
affect either. Things like throttle curves or expo setting can affect the
amount of a normal mix, however in a ORIGIN (#) mix these rate functions
play zero role....and the stick position is the sole activation of the mix
value.

You can still use the throttle curve and everything just like normal just
change the mix to a the "#THR" instead of THR and the trim lever will have
zero effects.

I know the manual on Page A-41 talks about this mix specifically. I don't
have the XP9303 manual handy but the X9303 (DSM version) is right here on my
desk at the moment. I was helping another guy on the phone yesterday and I
wanted to send him to the page in the manual that describes it.

So page A-41 talks about it and briefly touches on the origin mixing...But
they don't call it that. The Origin term comes from the 10 series and my old
way of doing things.

That should have you fixed up....

By the way throttle curve function is pretty good on the 9303. You can have
2 curves. I use one for windy and one for calm. This way I can flip the gear
switch if I find the calm curve is just a  little slow for the conditions.
The difference is I have the middle bumped up about 5-10%.

Works really well. I don't flip switches in 99% of the cases...but this is
one that has served well over the years. I rarely flip it in flight. I used
to do different models one for windy and one for calm. This made it all on
one model and I just check the switch before I take off. It they stays in
the same location for the entire flight.  If I find in flight its too fast
or too slow I can always give it a quick flip. Both he 10X and 9303 do this
really easy. Just assign a switch in the throttle curve menu and pick which
direction you want the switch to be in for the windy or the calm curve.
