+++ title = "INAV tuning tips" weight = 3 sort_by = "weight" insert_anchor_links = "right" +++ Here are some general INAV tuning tips and things I've learned throughout my builds. Keep in mind that these only apply to wings (and maybe planes), not quads:

  • There's a known problem with horizon drift. To ameliorate it, use set imu_acc_ignore_rate = 10. Setting this low is a good idea, but if it's set too low then the accelerometer will effectively be ignored and the horizon will eventually drift. To reduce the accelerometer's influence, you can also reduce imu_dcm_ki/imu_dcm_kp.
  • To make turns in automatic modes smoother, use set nav_fw_control_smoothness = 8.
  • Pawel says that the idea of the software LPF is to replace the hardware LPF. Leave the hardware LPF set to 256 Hz and set the software LPF to 20-30 Hz, with a looptime of 1k.
