"Thanks "Henny V"!
I forgot to mention it in my previous posts - so much to remember...
From my "tuning log" (sorry for formatting and Norwegian) I changed this earlier:

"Hi again!
Bad news from last days tuning 3.2.1. I have played with tens of permutations of ThrottleAccel P&I without satisfaction. Mostly lowering both by the same rate, ie. "P" half the "I" value. The pulsing decreases a little by lowering the…"

" Rob,
You nailed it!!
And it is embarrassing! With Arducopter 3.1.5 - after gradually changing "Throttle Accel" P/I from 0.750/1.500 to 0.500/1.000, and "Throttle Rate" P from 6.000 to 3.000 - the pulsing is gone. Just a very small disclaimer - the…"

"Congratulations "piku"!
While I am waiting for my new motors and props, could you do me a favour? Please make a short flight in Stabilize and Loiter/AltHold and upload a graph showing ThrIn, ThrOut and AccZ - similar to the one I made i my first…"

"Hehe, I noticed - thanks for your suggestion anyway! From the log you may see that the thr_mid already was set to 640 (recommended, same as ThrOut). Before your latest message I set it back to standard 520 and made a test - as we can see, same…"
"Some graphs from my tricopter:

"Have a look at my previous answer, please... "If you have a gimbal mounted it should be removed before attempting AutoTune, or at least secure all moving parts so nothing is hanging loose."
Instead of the camera you may want to put on something…"

"That's about one kilo heavier than my 550mm size scratch built hexa, so I guess my PID values wouldn't be of much help.
Still - a good starting point for Stabilize Roll and Pitch may be around 9.0 for both. My PI values for Rate on my hexa after…"

"The new Stabilize Roll value caught my eye - try lower it to 4.5 - equal to Stabilize Pitch. It looks like something went wrong during AutoTune. The ideal values depend on size, weight and number of arms of the multicopter, motor size and props etc,…"
