I recently heard a "rumor" that Sikorsky might start a project with 5 rotorblades on the S-92 to eliminate todays vibrations on the machine. I know the prototype 4 which was in europe had a heavier tail than the production machines and a lot of test equipement onboard.
I think this rumor is made on the basis of the feedback from the pilots who flew the machine and think it was to rough on ground and in the air.
Nick L. Do you have any knowledge of this?
