After using this setup for as my 'mode' switch:
it worked OK :)
But I decided to take it to next DIY level :)
There is 3 knobs on FlySky FS-TH9X radio, they are B5K potentiometers:
so we need to pick one of them that we going to replace with any available 6 position rotary switch.
(I have this one and it fits right)
Unsolder the 3 wires from B5K:
And remove the B5K from the radio :)
Next we need to make a small array of resistors that will act as B5K pot, when we switch to different modes.
The brown wire ( middle one on B5K ) feeds different voltage to the radio channel.
Now we need to add the switch that will connect the brown wire to each position.
And now we have solid 6 modes switch for APM and ACM :)
This is a "kitchen table setup" so if someone can measure better resistors value, pleas do :)
Its much easier than trying to setup some channels mix in this radio :)
Hope it was helpful.

If anyone wants the programming, PM me.
Slightly off topic, but it IS possible with the stock Turnigy 9X firmware to program a mix using one of the 2 position switches and one of the three position switches to get 6 positions. This is what many people do with other radios, but with the 9X it is pretty difficult to get the programming worked out to do it. I did it once (after fooling around with it for many hours) and I think it required 3 mixes. I don't have that programming any more and am wondering if anyone knows how to do it.
Please don't tell me to read the manual. I don't speak Chinglish (no disrespect meant to anyone except the person who "translated" the manual), and the 9X firmware does not actually do what the manual says anyway....
In ACM there is 'modes' option in 'setup' menu, it shows you switch position.
you can find the values here: http://code.google.com/p/arducopter/source/browse/trunk/ArduCopterM...
Yap, total can be more than 5K :)
also, you could use any other 'total' value.
it can be anywhere between 5K and 50K without any problems, dont go down off 5K
i wouldn't go over 50K - maybe the detecting system needs the current....
you could set the total value as 10K, then easily guess your output, because it will be 'decimal'
i.e. 1500K after the ground will be 150 (out of 1000) etc...
nice to see you made it.
actually this type of rotary switch in your picture is quite huge,
i dodn't get my transmitter yet, but i imagine it would never fit inside...
so i've searched for a much smaller rotary switch - should arrive soon.
how did you finally measure the pot value at each mode ?
and finally, how can I, with the serial monitor\terminal see the current selected mode ?
i'd like to tune the values while getting feedback at what exact value the 'switch' between modes is done.
that way i will set the rotary switch value to give out the middle value between two switching values, which will be the safest for not 'glitching' on to a 'near' mode.
