I haven't had problems with yaw servo. My biggest concern was 3S + 1000kv + 8" props = sluggish performance. I have to check if escs support 4S, to see if that makes difference, although the motors were already uncomfortably hot at 3S.

8" props and 1000Kv motor on you tricopter could be the problem - probably you dont have enough power. What is your AUW? Have you tried 10" props? Btw. high motor temperature can be caused by a bad tune.

Yes, I did try 10" too, but those motors did not have enough authority over them props. I just blame it on the motors. Poor quality. I have had same size motors, but different type (X2212) that performed so much better (on a different build - they came in as replacement for those A2212 which I reused on tricopter).

Finally got the "Next" on my windows workstation and linux laptop. Thanks developers!!!
Waiting for non-freezing weather and then lets the new tuning session begin  ;D

Just updated the Acroquad to the "next". Many thanks to f5soh to made it public  :D

The "next" seems to be quite different compared to the version 16.09. The flight performance is more solid and agile in once.
Today I did the basic tunning from the default setting. During tunning session I put the Gyro Noise Filtering to 0.000 and let the LPF at 180Hz. With these setting I got very responsive tune. The PIDs do not go to insane high values as it was in version 16.09. Rates with 360degs/s are rock solid even at flips and rolls. Than I raised the rates to 600degs/s I got huge wobble at the end of rolls and flips. There is more tuning needed and there will come the testing of acro+.
