I guess you see the question... what happens. Will the altitude stay the same as whatever the copter is currently at? Will I have normal altitude control, or will the copter rise to the preset altitude?
No. The copter ascends or descends to the preset (in MK Tool) come home altitude and executes the Come Home sequence. Come Home trumps AH is the short answer. Sorry for the bum answer above -- I misread the question completely. Thanks for calling my attention to that, Gary. Andy.
