Hello,
I flew with 2.9.1 for the first time this afternoon. Until today I kept manual control of the quad and it has performed nicely but I programmed several waypoints to give Auto mode a try and I turned Auto on at about 480 seconds into the log.
The quad followed the first waypoints around the field as expected but started to gain altitude after WP3 when there should have been a reduction of 2m of altitude to 8m to WP4. The log shows waypoints 4 being hit at the wrong altitude, it should have been at 8m. Then the quad went off for WP5 which should have been at 5m but the GPS shows was somewhere in the region of 150m.
To complicate things, the high throttle for the ascent caused a droop in battery voltage which the log shows triggered a failsafe mode however I was manually enabling RTL at that time and the ascent had started before the failsafe condition was detected.
I'm baffled. Any ideas what happened here?
PIDs are all (new) defaults for 2.9.1
Thanks

Hi Jonathan,
I have come here from David's thread. This does look like a noise issue. It looks like your noise caused the inertial vertical velocity to go low causing the height to climb. Based on your throttle output and climb rate it looks like you have constant vibrations.
I would suggest that you turn on your RAW logging and check your vibrations.
