Guys,
I don't mean to insult anyont so please don't take it that way. If you think DA is too expensive then don't buy it. You have your choice - buy a Zenoah, or Fugi. Deputy dog is right, We are a nitch market and regardless of where that market is (Lawn mowers or model airplanes) the price reflects a nitch market that doesn't descriminate because we are modelers. Coming from a Manufacturing background I honestly don't know how DA does it for the price they offer - I think they do a good job. You can bolt a lawn mower engine onto your plane if you want, but I don't think you'll be happy.
Regards,
