I'm a planker now getting into helis. I'm into forward flight and am interested in opinions. When flying a plane I would look at the wings to gauge whether the plane was rolled a little to the right or left. When flying the heli, I sometimes look at the rotor disc to gauge the same thing. I mentioned this to a club member who is strictly heli only and he said that I should never look at the disc, only the body and that I would catch grief from some heli pilots for doing that. I understand that the disc tilts during maneuvers or when roll or elevator is input, but I am only thinking of the heli as it flys by left to right or vice versa. Opinions? (And reasons if possible please)
