Autotune > Pid Settings Loiter non working

Hi, I had a really wild time configuring the mini APM right PID settings for my quadcopter ( which had parkinson disease ) right out of the box …

Still, some issues persist … when using the pitch the quadcopter’s response for stabilizing is “far delayed & too much”, it responds with the same angle in the opposite way instead of simple stabilizing … whatever …

Another issue I have yet, is the loiter mode, just seems to be simple stabilize, as well as the RTH, which sometimes results in a pure loss of control, then a simple crash …

Thanks for any enlightment upon my case
Regards, ben
