  • I found it , and i think that this is a bug in the APM Planner


    i thought that i activated the mode Alt-hold but is was RTL ( i read this with the CLI)

    Other mode i choose in the planner is Simple(it's there) but in real i activated Alt-hold.

    i suggest to look at this , it's happens with the First setup


    i fly .49 and vrsion of planner = 1.0.66
