TH9X Flight Mode Upgrade
I have the TH 9X channel transmitter, and the biggest problem I have with this remote is the most accurate way to change flight modes is by flicking one switch so whenever I want to change a flight mode I have to change flight mode 6 because flight mode 1 is always stabilize and simple mode, now this gets a bit irritating so one day someone posted a blog here of a potentiometer with 6 clicks and some variable resistors to each click on the potentiometer so you can define the PWM. I bought this for about $15 here and it was at my door in about 4 days, it was crazy. I bought the unsoldered version so I had to do some fine soldering.
Now the variable resistors has 3 legs (+) (Feedback) (-) it does not matter which way is the plus and minus. I took an old parallel cable from an old hard drive mounting and cut 6 strips from it about 10cm long and cleaned the plastic from it and soldered the two most outer wires from the bunch to the (+) and (-) and then Is soldered to all of the pins a piece of wire.
Once all that was done, I soldered the 4 inner wires to a number on the potentiometer, and the previous potentiometers brown wire where it said brown and the black to the black and red to the red. I then soldered the 2 most outer wires to the black and the red.
I then broke of the previous potentiometers plastic housing and drilled a bigger hole in the cover so that the new potentiometer can fit. Please note the extra smaller hole on the left hand side of the big one that I made, it is so that the new potentiometer fits snug into the hole.
I then fitted the nozzle thru the whole tightened it with a nut on the outside.
I then found a nice place to hot glue the variable resistors to the back of the cover so it is easy to come by with a screw driver because you have to adjust the variable resistors so that the signal is set to the correct PWM for the specific flight mode.
And then I started tuning the inner flight modes because the most outer two knob settings is always flight mode 1 and six and knob area 4 is also always flight mode 1. First set your aux-ch option to the following. Please note channel 5 is set to Pit trim.
I opened flight planner and started turning the variable resistors on each unit until the green on the dropdowns showed on the correct place.
An now I have 5 accurate flight modes to choose from without any hassle.
Hope it was help full and happy flying.

Good job! Made similar modification, but I used only 3 position switch.

3 is easy to manage, I will have to get some sort of sticker to define wich every flight mode is wich posistion.

If you are even remotely toying with the idea of purchasing the kit do it. I purchased one (not yet received) and can't wait to install it. I currently have my radio setup with 6 flight modes using the 3 position "Aux. 3" & the 2 position "Ail. D/R" switch combo. The problem with this is trying to keep the switch position settings straight in your head while in flight. Not to mention that when you install this mod you'll use the "Aux. 2" port freeing up the other two switches for other uses.
Current Mods: Smartieparts Backlight & Programmer. I love this radio… Can’t wait to see what they do with the 9XR.

I pulled the trigger this afternoon. I figured I am going to have 2 different drones. a quad and a trad heli so I would definitely get my moneys worth with the different flight mode selector switch.

Nice mod. I've had my eye on this but haven't pulled the trigger, yet. Let us know how you like it while flying.

I will keep you posted on how it is flying. I want to do the backlight as well it should be fairly easy.

Yeah, after doing this mod, the backlight will be no prob. I've done it quite a few times so ping me if you run into any snags.

Ha! That's hilarious! I'm actually the one selling that upgrade kit on eBay. Now I'm doubly happy to help out. :)
