Possible docs error: https://ardupilot.org/plane/docs/common-dshot.html

ArduPlane Plane 4.0

Hi all,

I’m new here… I have been messing about with BLheli_32 on Arduplane (mainly for the telemetry). I found that the documentation about SERVOx_TRIM reset with Dshot seems to differ from implementation.

In https://ardupilot.org/plane/docs/common-dshot.html - it says:

The SERVOx_TRIM value will be reset to 1000 if its a reversible output, or 1500 if normal output setup in DShot.

I have found (at least in Arduplane 4.0.7) that the opposite is true. In fact the SERVOx_TRIM value is reset to 1000 for Throttle servo outputs regardless of whether Dshot is configured, but setting the channel as reversible makes the value be reset to 1500. This makes sense since this midpoint value represents zero throttle for reversible ESCs.

So my read of this is that it’s a documentation bug. Can anyone confirm?

Thanks!

Martin.
