After installing the throttle pot, the other 3 will be basically the same. The pots in the base of the stick get the metal retaining clips in the post to help hold them in place, and the top one for the rudder control does not. Connect each sensor to its respective connector. Reminder to possibly use an angle base instead of a straight one on the pot near the left hand buttons so the sensor wires don't interfere with the board - test and verify.

After installing all 4 pots, you will need to adjust the angular sensitivity of each axis as well as the center point. To do this, you will need to power the joystick. If preferred, this can be done by connecting the joystick to any USB charger adapter, as all we really need is power for the sensors. Otherwise, connecting it to your computer should be OK - just be sure not to short the 5VDC to GND for any reason.

These are the targets for adjustment:

Axis centered: 2.3 VDC ± 0.1

Axis voltage low: 0.6 VDC ±0.1 (Pitch axis pulled back towards throttle handle, R-L Axis pushed all the way to the right, handle twist all the way CCW, throttle to full "-" or 0%)

Axis voltage high: 4.0 VDC ±0.1 (Pitch axis pushed forward towards away from throttle handle, R-L Axis pushed all the way to the left, handle twist all the way CW, throttle to full "+" or 100%)

In my testing, these represented approximately the limits where I was able to maximize the sensitivity of the joystick. Taking it all the way to 5 VDC or 0 VDC for the signal did not seem to work....it stopped responding to changing voltage below about 0.4 V, and above about 4.5 V. Further, when I first tested the system with the original pots, 0.5 and 4.3 V were the extremes I observed across all 4 circuits.

Connect a multimeter to the system, with the GND of the meter connected to the GND (Black) power header, and the + terminal of the meter reading the signal of the sensor (it can be read in parallel with any connections to the joystick). Begin with the slide of the pot in the middle of its range. Using a needlenose pliers, gently twist the magnet until the voltage from the sensor is about 2.5 V. Then move the joystick or throttle to one of the stops, and determine if the range of the sensor is too high or too low. If moved to a high voltage position and the reading exceeds 4.3 V, the sensor will need to be moved away from the magnet. If in high voltage and the reading is less than 4.1 V, move the sensor closer to the magnet. Adjust and repeat testing in both directions until the voltage is in range. If one side is in range but the other side goes out of range, the center may need to be adjusted by slightly turning the magnet to shift the centerpoint. The adjustment will be an iterative process, and probably took me about an hour to get all 4 pots adjusted to my satisfaction. Rudder adjustment is the most time consuming, as it requires at least partial reassembly of the handle each time to get a true feel for the adjustment of the pot.

Once adjusted, before reassembling the joystick, I recommend connecting the joystick to the computer and running a calibration. This will confirm that all axis are moving in the direction you intend and that none of them are reversed (with a magnet rotated 180º from where it should be).
