I’ve noticed that the TCAL_ENABLED does not work on this new 4.1.5.
Exponential valuesare not generated.

It works on my other copter on version 4.1.4

As you can see from the release notes above, the calibration code has not changed. So it is most probably a hardware issue. Is the copter hardware 100% identical? Or are they different? What are the differences?
