RE: Physics of the Funnel?
Next best answe Ihave in the physics of a funnel.
Think of it as drifting a car, as in Fast and Furious Tokyo Drift.As the front of the car startsto move left,you quicklysteerright causing the rear ofthe car to slide rightthus basically pivotting on the front of the car. With proper counter-steering the car goes around 360 degrees in a movement that would be similar to a heli doing a funnelwith the nose facing inwards.
If you were to give only left input on the TX the heli would keep going left till it eventually would just be doing a left aileron roll. Iam having difficulty wording my answer.
Just fly have fun and leave the physics up to the scientists hehehe LOLjust kidding
