"You log looks good, very low vibration. I would recommend installing a power module to monitor your battery. Other than that you appear to have oscillation on both pitch, roll, and yaw that can probably be tuned out by tweaking PID settings"

unstable roll axis

Hello all, the hexa i am flying with now is 1600mm, around 7kg without payload and 12kg with payload, and it is not stable at the roll axis. What will be the most common issue? I am attaching two flights,1. without payload 2018-03-022. 5kg payload strapped to the bottom 2018-03-05. https://youtu.be/hA1cP8OFWN4I am suspecting the PID gains being unsuitable, but are there any other concerns from the flight log?See More

"No I haven't because I feel like the drone is not flyable yet. Is there a clue to why the desired roll and actual roll diverged?"

Hi guys I'm testing a hex, with a wheelbase of of 1610mm, 30 inch props, pixhawk1. I am using Lightware SF11, and IRLock for loiter, u-blox GPS.I have tested this drone with loiter mode, and the first time it was flyable, without any issues. That was using [3.5.3], default PIDs.
