Probably a wise decision to shelve this one. I mean after all how many planes out there really fly unlimited on a zdz 80, just the 33% h9 planes, everything bigger requires a 100 twin, everything smaller works with a 50. I just dont see the market until more 90-98" planes come out on the market. couple that with the fact the zdz 80 is a popular powerful motor that more than likely would still be stronger/cheaper than the da 75 I wonder if this motor will ever see the light of day. What we really need are cheaper 100 cc twins, say sub 900 bucks, then people would quit looking at 75-80 cc's all together
