Autotune not work

Hi, i have read guide and see many Videos, but not work. This is my procedure:

  • Calibrate radio for check 100% stick movement.
  • takeoff in stabilize mode
  • Switch to AUTOTUNE
  • See in messages of Mission Planner AUTOTUNE START
  • Start to move stick 100% roll right - center - left for more than 20 times
  • Start to move stick 100% pitch up - center - down for more than 20 times
  • not see any progress bar or others…
  • switch to STABILIZE
  • See in messages of Mission Planner AUTOTUNE STOP
  • Landing and disarm

Repeat this operations many flyght but never change no P I or D or Ratio nothing !

what am I doing wrong? i see in the guide there is AUTOTUNE_AXES but missing in this 4.3.5
My plane is Delta only two servo Elevon SX and Elevon DX only ROLL and PITCH not RAW

thanks

From the wiki:

The autotune system only works while the pilot is demanding a rapid attitude change (above 80% of the maximum rate).

Make sure your stick inputs are quick. You don’t need to get full deflection of the stick as long as you are moving them fast. You should see messages on your GCS or Yaapu telemetry.

Post a .bin log file from the plane’s tuning flight if you’re still having issues.

Make sure that you have set the speed parameters ARSPD_FBW_MIN and SCALING_SPEED according to your aircraft and that you fly faster than ARSPD_FBW_MIN during AUTOTUNE. Otherwise AUTOTUNE will not be executed.

"you can AutoTune in most stabilized flight modes, such as CRUISE or FBWA/B, LOITER, or even during an AUTO "

PROBLEM SOLVED
