Good work Phil77, now we are talking The topic says "vs R44 piston" so of course, we are talking Robinson and not Schweitzer or Hughes or whatever.
As already stated by somebody else, these Lycoming engines date back to as early as 1940 so with some modern high tech German engines the story would look different was always my thought. But then again there comes the Cabri and they use a Lycoming engine again
Anywho, we also wouldn't get into an argument if a Mac is better than a PC better than a Playstation better than an Xbox 360 or a Nintendo Wii, and that was my point. They all do their thing and have their pros and cons and what was yesterday doesn't necessarily mean it's the same today.
N.B. the new (Notar-like) Neo kit helicopter uses a liquid-cooled 180 HP rotary engine (Wankel Engine) from an automobile. Interesting approach, as the advantages of a Wankel design vs traditional reciprocating piston designs are less parts, about half the weight, half the space, less vibration, more reliability and as you would say, less parts moving the opposite direction. In general, the Wankel technology has made a comeback in aviation in recent years.

Ok, the topic says "...vs. R44" but the article you've posted - and I was referring to - was quoting recips in general... The reason I brought other manufacturers into the discussion was your article. The author was comparing his fine products to schweizer and others and how superior the idea of derating is.
Although a slight threadcreep I think my point is still valid. Ask a company representative to write an article about his aircraft, fine; ask him to write an article about the engines they are using, ok with me; but don't ask somebody who sells a certain product for a living to compare it to the competitor's and expect an unbiased report
