Tracy, I totally agree abou the "spread" of rpm engines can have. 3W's have, for years, seen 200-400 rpm difference in their engines output, depending on a number of factors. One or two of my own personal engines exhibit the same tendency to not always give me the same power output. . losing as much as 200 rpm with the same prop for no apparent reason, then never quite recovering their former power level even though a number of things are changed to try to get it back up. Others are a total beast compared to their exact counterparts, flown by other people.

Day to day power numbers vary, everyone knows that, and there will always be "weaker" or more potent engines of the same make and size. What has come to issue here is that yet another uninformed person is trying to denegrate a product he has NO knowledge of, as this same person does for anything he does not personally use.

The Da100 is a fine engine, as is the 3w106. I'm just glad that Keith has gone through the effort and worked his BUTT off to give us a third choice, one that is (by all standards) a better choice than it's competitors.
