A while ago I was told by a flying mate of a demo he had been shown on his R44 conversion with the RRPM down at 70% in the hover, I was horrified and emailed my tech man at Robinson whose reply was quite succinct and went along the lines of
Why did they do it ? and We recommend replacing the blades now.
GS
I must be missing something here. Why would Robinson recommend replacing the blades just because they were run at 70%?
What's the difference between holding a 70% hover on the cushion with power and
when you perform a throttle chop in the hover, you hold the lever where it is then raise it to cushion the landing. Both maneuvers would probably see 70% rrpm before touch down.
