Thanks for all the very informative replies. I have learned a lot from this thread already. I have noticed that all of the planes I'm looking at (mostly 27% Yaks) all have the templates for 3W and DA included with them. I have never built a gasser but I am sure that it is not hard to adapt a Brillelli, or a Taurus to one of these planes. The taurus does have an unusual looking backplate though. I am hearing a lot about the DA having a sloppy midrange as well as some deadstick problems. That is what makes these forums so good for the unexperienced. I was under the impression that DA was the Cadilac of gassers before I asked the question that started this thread. I also never even heard of Brillelli or Taurus before this thread, and it is nice to discover new engine choices and hear so many good things about them. I own and fly many glow planes and I am really excited about entering into the world of gassers.
