Full stick Yaw aggressiveness

ArduCopter
1

Hello…

I am having trouble controlling my drone’s yaw as it is giving an aggressive Yaw attitude. The problem is present when the drone is tested on yaw full stick input. The drone gets a tendency of maintaining the yaw movement yet the stick has been released posing an issue on the drone not instantly stopping to its neutral point. However, this only occurs on full yaw input and not when the stick is pushed smoothly. How can I reduce the aggressiveness of the yaw attitude?

Here are few parameters of the drone as well as the navlog of the test:

Drone specs:

  • Quadcopter
  • T-Motors
  • Orange Cube
  • Herelink airunit

This is a quadcopter running arduplane and flying in FBWA mode?

It is a quadcopter yes, but running on arducopter as set up in the mission planner.

You tried it your way. It did not work like you expected.

So how about trying the ArduPilot methodic configurator software to solve the problem with no trial and error?

Surething… I am about to adjust the:
ATC_RAT_YAW_IMAX parameter to increase the maximum yaw output.
ATC_SLEW_YAW (-50% tune), and the
ATC_ACCEL_Y_MAX (+50% tune)
to see how it responds

That is just more trial and error. And some guess work.

That is fine, after you have a good starting point, that you currently do not have.

Do the process first, and do that kind of fine tuning afterwards. Not the other way around.

Then that’s not the right log.
