Trige, many many thanks for the reply bro !
If gains are suspected culprit then the same skywalker plane with which I have done more than 200 successful auto mission flights with APM2 only should have not been.
I mean I never initiated RTL in guided mode in any of my flights with APM prior to 3.4.
Prior to this crash, the this skywalker plane with same APM2 has done few successful flights in auto mode without any issue and that is too with default parameters. Below is link to some of very successful long missions with Skywalker with default parameters in APM2.
Below is the telemetry log file’s video clip of small portion of this flight in which crash happened.
I mean I have seen that Skywalker always does well with APM2 default parameters. But this does not mean that I should keep on using default parameter.
I will do as you suggested. I will change the parameters approximately to what you suggested or autotune it.
When the APM2 bug fix you are planning to release ?
