Autolaunch topic with 7.0.0 compared to 6.1.1 (fixed Wing, Funjet)

[druckgott]

Current Behavior

With 6.1.1 after some optimisations the autolaunch worked quite good with the fixed wing funjet Now I updated to 7.0.0 and the funjet rotates quite much. It´s not realy smoth and i nearly crashed.

Steps to Reproduce

Flash 7.0.0 with same diff of 6.1.1

Expected behavior

same behaviour like 6.1.1

Suggested solution(s)

attached the logs it looks so different see below LOG00045.TXT

Is there anything changed between the autolaunch behavior on both verisons

[MrD-RC]

Nothing has changed for autolaunch in 7.0.

Are there any other changed which can have influence the Autolaunch roll behavior

Here is some refacroting where Code in Autolaunch is changed or not

* 7.0.0
  [LOG00057.TXT](https://github.com/iNavFlight/inav/files/13998653/LOG00057.TXT)

* 6.1.1
  [LOG00044.TXT](https://github.com/iNavFlight/inav/files/13998648/LOG00044.TXT)

Looking at the logs.. It appears from the 7.0 log, that you moved the roll stick to full deflection, straight after launch_in_progress began... Which cancelled auto launch. And caused it to roll rather abruptly from looking at the setpointRate[roll] and rapid i-term roll accumulation.

[druckgott]

the point is that on 7.0.0 it rolls much more then on 6.1.1 is the feeling. We did many tests on 6.1.1 to get it to a good behavior. Then i flashed to 7.0.0 and all 3 starts it rolls quite mutch and I put my handy to the stickts to roll it back. LOG00057.TXT

And we do not unstand why it´s so differnt that it alrady rolles so much during autolaunche until sticks are comming.

[Jetrell]

As soon as you move the stick past nav_fw_launch_abort_deadband. It will cancel auto launch. And in your case, become Horizon mode. So we can't seen from logs 57, what would have happened if auto launch had continued. While in the log 44 from 6.1.1. Auto launch was completed.

That just looks to be cleanup for multirotor throttle tilt compensation.

But the throttle scaling was refactored.. Including launch idle throttle changes. https://github.com/iNavFlight/inav/pull/9287 So it may be providing slightly less available throttle in 7.0, with the same launch throttle setting from 6.1.1... Which might explain why the roll axis felt lazy at launch.

[druckgott]

Ok why is this done does this makes sence or whata the background?

So i mean the less throttle

that change only affects multirotor not fixed wings.
