Hello DIY Drones community,
I'm seeking some assistance trying to figure out the source of wobbliness on my Hexacopter. I've attached the log here. What happens is the drone will take off and it seems relatively stable. I can generally make gentle pitch and roll commands and it responds as expected. Except after a few seconds I will start to twitch on the both the yaw and pitch access. The copter will be hovering and without touching the sticks it will take a small dip in one direction, then it will likely dip back the other direction. Over the course of a few seconds the copter will feel more and more unstable until I bring it back down.
I was flying a virtually windless environment so that wasn't the issue. Also, it seems from the logs that I've kept the vibrations very low, so I don't *think* that's the issue, although I would appreciate it someone could confirm that. The Pixhawk is mounted on top of earplugs.
I should also note that the copter felt very twitchy and unstable in previous flights, so I lowered the values for both the "RC Feel Roll/Pitch" and "Roll/Pitch Sensitivity" in the Config/Tuning section of mission planner. That resulted in a significant improvement.
I would appreciate if someone could take a look at my logs and give me their opinion. If you compare Roll and DesRoll (and same for Pitch) you can see telling deviations. But that's about all I know how to look at.
Thanks for your help!
