If Ray Prouty said that about the design of the Robinson rotorhead either he had not fully examined the problem or, if he did, he had his head up-and-locked.
A ninety degree pitch horn could never have been used on the R22/R44 rotorheads unless they got rid of the coning hinges.
If you would refer to my response to Frank Robinson I stated that I would buy the positioning of the cone hinges that resulted in the eighteen degree offset as a means of reducing certain pitch coupling. However, the lead in to this thread is that there is no 18-degree offset of the two parts of the swashplate.. The rigging is done with the pitch links over the lowest/highest point of the stationary swashplate which offsets the blades by 18-degrees. This makes Frank Robinsons' argument go away and as far as I am concerned, Ray Proutys' input is moot.
You mentioned having to compensate at higher speeds, discounting transverse flow effect, what compensation are you refering to.
Before you answer that I am including a response by The NR Fairy regarding my statements about the impreciseness of the Robinson cyclic control. This was in response to my claim about having to compensate for the so called 18 degree offset.
