90 degree pitch horns plus coning hinges.
Correct. The situation you describe would occur with the pitch horn crossing the coning hinge. What I had in mind was to move the coning hinge to the same point as the teeter hinge so the pitch horn would not cross the fulcrum. Please tell me if this would correct the situation.
Bear in mind I am not an engineer or designer. Just a thick pilot.
I have a horrible feeling we agree over the phase angle thing.
I suspect that delta3, if I have understood DJs explanation, means that the blade only flaps over 78 degrees of the 90 degree phase lag so the EFFECTIVE phase angle is 78 degrees.
Perhaps an issue of semantics.
Has anyone else tried flying an R22 left handed and found it harder than expected?
