The C20B is rated at 420 HP for take off, 385 HP max continuous.
Yep that's good, but it sounds a bit like one of Kiwis talking about the R22 Beta II in one of their videos;-
It develops 180hp!
Yeah but you can't use it all can you? The little blue book that Frank gave us with the machine tells you that if you care to read it.
Could you let us know what is the power rating of the RR300 at 8,500 feet? Any better than 220 hp max cont or 285 wide open (can't remember whether that was 2 or 5 minute limit) and we have enough to fit the little blue book, why it might even be lighter than the C20B and give us a weight saving to boot?
