I have got a small 3d plane Komacro(wingspan about 40 inches 42- length. I am looking for an engine for it. All up weight less motor and fuel is 850g (30 ounces). I want it to hover and pull out. I was thinking of a magnum .28, mds.38, os 25la or mvvs .28 OS max 25fx would be the best but it costs too much over here. Maybe any other choices?
