I just flew my maiden flight with my new, totally custom octocopter. Everything worked really well except that I entered into a heavy oscillation, which I was able to recover from. Does anyone have any advice for PIDs for such a frame? My frame is all carbon fiber, long arms, heavy lift motors running large slow flyer props.

Hi Adam.
I've got a failry big octo, droidworx AD8 HL + Photohigher Av200/360 cam mount, about 4kg without camera, I've messed with setting a fair bit and find that lower P rate and higher D rate works well, thus the copter is smooth yet with the higher d rate still gets back to level well.
currently my copter is set to P of 2 and D rate of 0.2
It also depends what you want to do, with us shooting mostly video the smooth motion is great, but I've also played with more 'normal setting like P 4 and D .145, which I think is default.
Hope this helps.
Bump. Anyone with a heavy setup have PID advice? I'm going to start tuning tonight. I will post my results here in case anyone else needs similar info.
Also, I did read through the wiki... I am more looking for some peoples personal experiences with similar setups.
