I have a QX7 that I put Hall Sensor gimbals in a couple of years ago and I am now having problems with Yaw. I connected two different quads to Betaflight and the yaw control on screen is not always following the stick. Sometimes its delayed and then jerks to position, somtimes I have had the stick at full deflection and only getting partial movement on screen.

Is it possible it needs cleaning or something?
Throttle, pitch and roll are fine.

I assume that you've tried re-calibrating the gimbals?

Hall sensors don't usually go wrong. If re-calibration doesn't fix the issue then check that there isn't some metallic debris near the sensor that may be interfering with it's operation. Also try re-seating the gimbal connectors inside the transmitter by unplugging and re-plugging them.

I dug out the original gimbal and that one worked fine.

I took some air and blew the Hall Sensor out and reinstalled... It is now working again. I don't know if it was the cleaning or the plug being re-seated...

For a few minutes I thought I had a reason to get my new Radiomaster but now it will have to wait.


EDIT: I forgot how much difference there is between the original gimbals and the Hall Sensors.
