Mounting any 2 stroke engine isn't recomended. The engine is pretty hard to start unless the plane is inverted making the engine upright. Also in most cases the fuel tank is higher than the carb and this causes the fuel to siphon into the engine. When that happens the fuel douses the glow plug and the engine quits. If you must do this, an on board glow plug driver helps. 4 strokes have a different design and aren't as bothered by inverted running. [8D]
