i've been following this new conversion by the well known, sub converter, jan eggenfeldner.  this time he's using the honda fit core with mods to make it airworthy, using all his knowledge from the sub experience.  he's located his factory in central fla & seems to be doing really well. he began shipping engines back in early 2012 & now has flying machines from several big kit sellers (incl just ac  & kitfox which are very similar to the avid design. )  he just added an all metal kitplane from new zealand (i think), that seems also to be related to the avid design, with folding wing.  visit his web site for all kinds of vids & info.  if i were ready to buy an engine for my fat avid i think it would be jan's viking. seems a good fit for the larger plus size. jan had a display at sun n fun.  fyi.  john bowman, prvlle, la.
