Irregular Behavior Arduplane 4.0.2

Just upgraded Cube Black to 4.0.3 from 3.9.2 on V-tail plane. When holding rudder full left, the control services cycle from middle (1500) to full rudder left (about 1380 ) very quickly.

Had a similar problem with 4.0.1.

Everything works fine with 3.9.7

Logs or it didn’t happen…

And for an issue like this, you are best to post on the 4.0 post on the ardupilot forum
