I saw that in ACRO mode, the airplane can make a looping, which includes vertical flight control. Is that correct?
And if the arduPlaine controls a RC 3D model (that can act as helicopter in vertical position), in ACRO mode,
I am wondering is it possible to have a flight mode that will keep continuously the airplane in vertical position at constant attitude ? Is there some mode that can achieve that, if not, is it possible to extend the arduPlane in that direction, or the arduCopter should be used for that kind of flight modes?
