Tarot X6 - does autotune just suck on large hex's?

Does autotune just generally not work well with large copters that have low KV motors?  (using 6S, 320kv, 17x5.5 CF props).  Honestly I think it flew much better with the default settings than what…Continue

"my 690 hexa´s pid´s goes way off with autotune. Tried the AT many times and allways without succes. It flies quite nice with defaults, just little finetuning with "save trim" feature and some other minor changes on parameters."

"There is a large difference between  say a 550 hex and a 900+ hex. Not that I have flown either plane, but I always refer to smaller multirotors as small and nimble and is like flying a P51 mustang or big and stable is like flying a B52 bomber.…"

"Thanks Craig!  I set the PIDs back to default and the roll/pitch is quite good with standard parameters.  I messed with the ch6 tied to yaw P and D and it's a bit better now (at least I could see it making a difference), but still…"

"I've never had "great" results using Auto-tune to be honest on ANY sized flying lawnmowers. I have found that if built correctly the closer to stock pids I run the better it flies. On my T960 with 320kv motors @ 17.5 CF props it flies…"

Tarot X6 - does autotune just suck on large hex's?

Does autotune just generally not work well with large copters that have low KV motors?  (using 6S, 320kv, 17x5.5 CF props).  Honestly I think it flew much better with the default settings than what autotune found for it...and the yaw is super slow and delayed.  Is this just common with large hex's and the pixhawk? Anybody have experience with this frame and care to share the PIDs that work for them so I can at least have a good starting baseline?Failing that, any suggestions on how to improve…See More
