I am thinking about getting a sig hog bipe as a 3rd or 4th plane, What would you recomend as an engine for it, I really want to be at or under $200 for the engine, a lot of people recomend a 4 stroke, I just have problems spending that much more money on an engine. Would I be happy wiht an os 70 ? or how are Saito engines? I have not had an 4 stroke yet, I a bit nervous about 4 strokes. Or should I jsut get an os 75 2 stroke and be done with it.

Thanks

Jon
