Razorback you mention this is the latest technology where is the technological breakthrough? Is it the materials? Is it a new design if so whats new? Have they skimped on anything (Cooling fins) I dont think you can compare this engine to a ZDZ brick?
ZDZ Brick?? ZDZ are a proven motor with a strong reputation. Have to say, there is a lot (maybe too much) of focus on weight of 100cc and bigger engines, and I think it is unwarranted. Frazer Briggs flies a 3M Extra with a DA200 4 cylinder . . I haven't seen the actual weight of this motor BUT believe me it will be heavy . . it has to be (More crank, 2 more conrods, 2 more pistons, 2 more barrels . . Oh . . and more "cooling fins" . .
). If you have ever seen Frazer fly that thing . . it looks far from weight affected and seems to defy gravity (He won the 2004 Tucson Shoot-Out with it by the way).
Some extra ounces on models this size can go very much un-noticed. While not necessarily the case, a heavier motor can mean more solid contruction ! ? ! Focus more on plane selection, flying and constuction skill, and less on engine weight (within reason) IMO . .
