Nope, look a little closer and you will see me decend,as I'm setting it up,and climb as I circle around,and pull away from the tree! A helix can be 180,360, reverse,start out high and go low,while comming in closer,ect. The "helix" is nothing more than widening the circle,while climbing,or decending,be it 180 360,ect! Circling around a object (nose in) at the same altitude is called a funnel,or as DJI tries to state it,a POI! These manuvers have been done for years by heli pilots. The Helix "mode" is DJI's idea of what a helix is,like the term they use for the Transmitter the (RC)?
RC means Radio Control,not "Transmitter"!
