Collective Question?
I hope this question makes sense:-
In most Helicopters the collective lever is there to allow you to increase or decrease your altitude, by pushing down on the lever most Helis that I am aware of will start to descend through the erosion of lift by the blades being fined off or placed into a nil pitch situation.
Do any helicopter have the ability to actually tractor down in other words we have pitch change and power to go up, is there such a thing as reverse or negative pitch change, with power remaining up but craft rapidly going down under power?
