Is it normal to have 1000 units of throttle travel with C-MUK Hall sensor + TUSBA?
-
The throttle pot in my Cougar TQS recently started acting flaky, so I replaced with a Vipergear C-MUK Hall-effect throttle sensor. I’d purchased the sensor a year or two earlier, thinking I’d need it someday, and someday recently came.
My Cougar does have the R1 resistor, so I installed a wire to short R1 on the PCB, as shown on page 2 of the C-MUK intallation guide:

I placed the magnet as close to the sensor as possible without them touching each other, I think the magnet is within about 1mm distance of the sensor.
I also use a TUSBA R2 to connect the Cougar TQS to my computer.
Overall, the throttle seems to work well. I haven’t noticed any “spikiness” or other flaky behavior, which is great.
I haven’t yet tried the AAR mission, which I suppose will be the “acid test”… although I know I should give it many, many tries before I pass judgement on the sensor, since my own skill-building will the more important factor in AAR refueling success.
Here’s what I’m wondering: Is the behavior shown in these screenshots normal?
This first screenshot is with the TQS in the fully-physically-back position. The second screenshot is with the TQS in the fully-physically-forward position.
When I was using the old, original throttle pot, the picture of the throttle, as shown in the RS_HID_DEV_TOOL program, would appear to be all the way forward, when I had my TQS fully physically forward. But now it is depicted as being only a little ways forward, even though the actual physical throttle is all the way forward. There appears to be a difference of about 1000 units of measurement (as reported by the RS_HID program), between the real-world-fully-back position, and the real-world-fully-forward position. I’m embarrassed to admit I don’t know what this “delta” was when the old potentiometer was in place.
I’ve re-done the calibration with the RS_HID_DEV_TOOL program, and the behavior stays the same.
I believe the TUSBA R2 is a 12-bit device, and 2^12 is 4096. The antenna elevation pot, and the MAN RNG pot show “deltas” which are both about 4000 units in size. But the throttle shows about 1000.
This might be completely normal for a C-MUK Hall-effect sensor + TUSBA R2 combination. It might be normal, and might not be any `handicap’, I was just curious if this is what other people see, as well.

Hi!
You have the same question I had when I installed the hall sensor. This is normal.
The hall sensor moving distance is so short. Mine is shorter than yours.
You are lucky your sensor works perfect without any problem at the first time.
I had a problem which my throttle input was opposite. I thought my hall sensor was defected.
Mine works only after I pulled out the magnet from case and put it opposite. -
I placed the magnet as close to the sensor as possible without them touching each other, I think the magnet is within about 1mm distance of the sensor.
I see around 1400 units, but I aim to get the magnet and sensor as far apart as possible.
