Just to muddy the waters a bit more -- I don't have a VMAR model, but a good friend has a VMAR Harvard II (his second one- he lost one when it tip stalled in a landing approach). It is powered by an OS .46 FX & it looks great & seems to fly pretty well. It is about 8 wks old so far & hasn't broken anything yet. I have flown a few "dogfights" against it with my Blackhorse Spit & it doesn't fly nearly as well as the Spit, but it still flies well enough for the owner to like it. Maybe they have improved.

The Blackhorse Spit was not recommended either, but with a few stab/elev mods, it has turned out to be a real winner.
