RCOUT Oscillation During Flight

General
1

Hello everyone,

I’m looking for some guidance regarding an oscillation I’m observing in the RCOUT values during flight.

I have already taken multiple flights, and the drone is flyable, but I noticed that the RCOUT values are oscillating approximately between 1100 and 1900 during flight. I would like to understand what could be causing this behavior and what parameters or logs I should investigate to reduce the oscillation.

Hardware setup

  • Flight Controller: Pixhawk
  • Firmware: ArduPilot 4.6.3
  • Motors: T-Motor 920 KV
  • ESC: Holybro Tekko32 F4
  • Propellers: 10-inch
  • Configuration: Quad

I have attached the Flight log for reference.

You need to setup RPM filtering, LPF probably is not enough.

Thanks for the suggestion. I’m quite new to RPM filtering in ArduPilot, so I’d like to understand where exactly I should configure it.

See section 7.1.1 of the ArduPilot methodic configurator software tuning guide.

It explicitly solves this issue

It looks like you were directed to the Methodic Configurator previously and apparently ignored that advice. If you had this craft would never be running an Auto Mission in this state of tune.
