Zenoah is a bit heavy, oldish and not so powerful engine anyway...

We've heard all of the stories about Zenoah being overweight, underpowered boat anchors. There is thread after thread after thread regarding such comments. Most boil down to a realization that many folks are comparing EI engines of a smaller displacement to the zenoah with mag ignition, and use weight as the overall deciding factor. A very common comparison would be the G62 to the latest 50cc engines out there. This is not an adequate comparison at all. The cost of some newer EI engines is still higher than getting yourself a zenoah, converting it to EI, losing a pound or more of weight, and then you have something to compare to. Put any 26cc next to the G26, equipped with EI and a properly tuned pipe setup, and prop for best thrust (mezjlik 18x6) and see how things compare. Can every 26cc engine readily available for our hobby spin that prop on a pipe at 10 grand? What you'll find is that most don't measure up to the virtually bullet proof zenoah, and those that do measure up, don't win the battle because they are significantly more expensive by comparison. Even in the unfortunate event that both engines dirt dive....you just can't beat the readily available replacement parts for the Zenoah, available through various sources, rather than having a limited source for parts, and finding that they are more costly to replace. I'm not strictly a Zenoah fan....I have a thing for 3W's, ZDZ's and the new DL as well. I don't happen to have any DA, but I know they are a good product. Bottom line is, when setting up the engines to compare 'apples to apples'....Zenoah has a very competitive place in this market, and has proven itself worthy of maintaining a good name respectively.
