I'm looking for this info too. I got some results by not removing the resistor and just 'replacing' the switch with a 10k log potentiometer, but it's not 1k at half turn like the manual says. one side of the original button wired to the center potentiometer post, and one side to one of the outer post. I get a lot more movement on one end of the pot than the other, although I still get a full range.
I'm going try bypassing the resistor and using a linear pot, once I get them, on another hacked radio to compare. but I have no idea what I'm doing.
through my meddling, I believe r18 is the correct one to bypass as well. Im using a gt3c. my board says rev:1.6. I'm on 0.6.2 firmware.
Stuff to double check. If I switch from CH3 button to CH3 pot, it will default to throttle trim. Calibrate Ch3 in the calibration menu (Hold full right steering + hold enter). You are only calibrating full left and right for CH3. if you have it wired up right, you'll see the number change when you turn it. Check end points on the desired channel.

I have the radio updated to 0.6.1 firmware, I have it set to use ch3 as pot in the global config, and I have ch3 set as ch3 on the radio to the receiver. Now, I just can't figure out the wiring. Nothing I do gets the pot working on channel 3,im checking through the calibration and using smartproproplus on the pc directly to the controller, and to the Arduino based receiver adapter I made.
Where do i hook up the wires of the pot on the controllers board? Which resistor do I eliminate? I'm assuming the resistor is labelled r18, as its the one that is inline with the ch3 button, according to my multimeter. Some help would be greatly appreciated. I need another real axis added to this controller for one of my rc projects. Thanks a bunch in advance.
