Hi everyone.

I still tune PID`s for my M4 board on TBS Discovery frame. Current PID`s allows to hover without oscillations, but when I`m trying fly agressively - quadcopter starts oscillating. It looks as need to configure TPA (Thrust PID`s attenuation) that available in many other firmwares, but I can`t find TPA in Autoquad.
This option exists?

In which mode do you fly? Can you post a video so we can see what's going on?

Problem exists in manual and pos. hold modes. I cant make video. Sorry.
Just for info: my quadcopter is seriously overpowered. Auw about 1400g. Total thrust abobe 4000g.

Unless your PIDs are near default settings you will not get good control. The main reason for not being able to use defaults is VIBRATIONS. With your type of frame the only way I could get vibrations under control was to connect all the motors with a tight string. The string dampens the vibrations. The TBS frame will teach anyone how important controlling vibrations is.

What is default PID`s? As I can see, default PID`s in AQ6 is different from default PID`s of M4. I used on TBS frame Naza M lite, Quanton with Taulabs firmware, Naze32 full and not any vibrations issues was observed. May be AQ does not have LPF filter for ACC/Gyro?

Connect your AQ board to the QGC. On the Config page look at the Onboard Parameters for the Default button.

To get precise control you need good inputs.

It is Defaults for brushed motors as I understand. 32000 D is too much. I roasted my brushless motors with default M4 PID`s.

Here are video where you can see light rapid oscillations in position hold mode. Could you tell me how to fix it?
