Autotune problem in Pixracer

I am also having no luck with autotune in Pixracer , whether assigning it as a flight mode or using Ch 7 or Ch 8, with the sticks centered and the UAV at a still hover. FWIW, I notice when I generate an Auto Analysis, it shows “Autotune N/A” in the header.Running APM Copter V3.3.4

It’s a 560mm quad, 2600g AUW, 700kv motors, 4S, Hobbywing 40a ESC

Flight modes I have tested with excellent results:

  1. PosHold
  2. AltHold
  3. Auto
  4. Circle
  5. Super Simple Mode
  6. RTL

3.3.4 or 3.4-rc1? If the latter, then share a log please.

The version on the taskbar reads: APM Copter V3.3.4 -pixracer ( cce6cd30).

I’m new to the board - can you tell me how to post or upload the log file? Thanks!

EDIT: Here is a link to the log file:

I’ve separated this into a new thread because that one is for Copter 3.4.

Thanks Francisco, and my apologies for posting in the wrong thread.
