I have a fairly large quad (4s, 5000, 13" props, APM2.5, V3.2-rc2). I have it well tuned and very smooth for Stable and Loiter modes. The problem is in Auto mode only. During climbs and transitions from one WP to another it twitches in pitch and roll. You can hear the motors surging. It’s not anything that would cause a crash it’s just not steady and smooth. During long legs after it steadies out. I have tried adjusting the basic stability parameters and motor parameters but it has no effect on this. The thing that gets me is that in Loiter I can climb, descend, accelerate and stop rapidly and it’s perfect.
It seams like it’s has too much gain in the logic that makes it accelerate and decelerate during a mission. I don’t see any gains that are specifically related to Auto mode? It’s not obvious to be what parameters I need to adjust. Please help!

Hi,
some of us have the same issue, here:

Turned out to be a 3.2-rc2 bug.
Today I loaded 3.1.5 to see if that would help. This is the first time I have flown this version. I was amazed at how much smoother it was compared to 3.2 beta. 3.2 definitely has some bugs that need working out before it’s ready for general release.

Has anyone noticed a difference in mission stability between 3.1 and 3.2? Does anyone thing that loading V3.1.5 will help my problem?
