640cc Uber Pimp
@Xpress may I ask you a question you are presently flying the the plane with a ZDZ180 I believe. Looking at the ZDZ web site they also make 190 size. Why did you pick the 180 from the spec sheet the are the same weight and everything else except for the displacement. Did you prefer the 180 and why. Just looking around for a new motor but know very little about this brand except what you have writing about the motor on this site.
