During landing, my quadplane overshoots the home position, then “reverses” for it to start descending. Initially I thought I should increase q_loit_acc_max but even with a 50% increase (120 to 180) I don’t see any improvement.
What parameter should I change to ensure the quadplane does not overshoot home position. @tridge
the Q_TRANS_DECEL is indeed way too high. The current value is 2.0. I suggest changing it to 1.0 to start with, and lower it some more if you still get overshoot
I’d also suggest you look at this tuning guide: https://ardupilot.org/plane/docs/quadplane-vtol-tuning-process.html
you seem to have skipped some of the basic tuning steps
the TECS.hdem and TECS.h do track each other nicely in RTL mode:
