The best Nr for EC120B
Hi
I have just started to fly completelly new EC120B. The fuel unit is set to keep Nr around 413 to 415. I am not so much happy with vibrations, although another EC120B, that I was flying on (aircraft with around1200TT) aslo had Nr around 414, and the vibrations were worse.
But I have read somewhere, that 407 Nr are the best for heli. Is that true?
