A question I have not seen asked. For those of you that have experience with several manufacturers gas engines.

Between the brands (DA, ZDZ, 3W, Brison, BME, etc) have you noticed any particular tendency of one engine to vibrate any more or less than the others. Realize this is subjective, but would be interested in your comments.

I don't have much gas experience -- I just started flying a Brison 3.2 and my DA-50 is still in the box... However, I was pleasantly surprised how little my Brison vibrates. It's much smoother than my YS 1.20NC...

DA twin is smooth, BME and 3W twins shake. zdz single is pretty smooth for a big single. My brison is a single also so it has some shake to it too. None of the engines are of any concern though..

If it makes any difference, I am very pleased with how smooth my DA-100 is. Just a flip and fly engine that runs great out of the box.
