I´ll try to set the altitude = the last waypoint  like I do using the Majestic Q400.

Correct It seems unreal to set  ZERO - but.

Also I set the stability a little bit higher ( nose up) than calculated.
Last test no need for speedbrake.

Thank for for the advice.  Nice to be on the right track...

Enclosed a photo  - OK landing - beautiful repaint . thank you
