Hello,
Maiden flight with recently built Hexacopter (F680 frame) using Pixhawk with 3.4.6 FW and I have problems with Alt Hold and RTL when trying to land. Copter climb suddenly when close to ground trying to land.
I have built some similar copters (not so big) with APM and never had this issue.
I'm thinking about Z axis vibration or barometer problems when close to ground, but I haven't so much experience with dataflash logs to figure out the exact problem.
Attached is log. You can see throttle is at minimum almost all flight but copter didn't land and altitude is erratic.
Hope someone can take a look and give me some clue about the problem.
Thank you in advance.2017-05-17 17-43-03.bin (1.7 MB)
