Thought I'd chime in as im building a Cozy.. anyone can see the problems in your decision as you probably do yourself..In my opinion I would not buy that Long, it has many problems to say the least, 20yrs since it flew, engine is very suspect, the build quality is not known, it flew for 1 hour? maybe red flags there...wings or canard might have problems...Maybe the airframe might be ok, just ditch the engine and get something else..who knows? If you want a Long Ez or Varieze or Cozy, you could buy one from the States and get a better deal doing that...(share a container etc)...or if you are like me and like building stuff, the Open Long Ez plans are available for anyone...http://forum.canardaviation.com/showthread.php?t=6129
