It seems that with each revision the default PID's seem to change. My question is are those PID changes because we found a better match or the testing airframe (assuming default arducopter airframe) or are their actual code changes that require higher PID's.
The main reason i ask is currently i fly two tricopters. One on jacob's frame and the other the pro tricopter kit with long arms (19 inch). A revision or so ago the default stab roll/pitch P was 4.0 and rate roll/pitch was about 0.13. I had to decrease my stab roll/pitch P to 3.45 to stop oscillations.
Now, today i update and default stab P is like 4.7 and rate P has seemed to increase too. Has enough changed in the 2.0.47 branch that would require me to re-tune all over agian or would going back to PID's that work well on my frames be ok?
Thanks a ton
