My apology to the two of you. I was not referring to the peresent or past Rotors, I was talking about the research or experimental machines the ngineers are working with. They are trying for more capacity etc. I have no doubts about what you are saying, but we are now trying to go to the next level. I think the twin-rotor has the best chance of doing that. I am not going to back down from my original thought that the TR's have enormous capacity and I don't think we have used it all up yet.
