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 it? Especially yaw performance... it suckeths. Tuning large copters is hard because I really don't want to crash this thing... Using copter 3.3 fwiw.
