Nucer, you are so correct. Either make of engine has its good and bad points. I particularly like the fact that you can get good power out of the four strokes at less RPM (much quieter) and they allow much neater aerobatics at lower speeds. Now some people just like high speed and noise so they will like two strokes better; nothing wrong with that, let them have their fun also. I also like the fact that the four strokes run twice as long on the same abount of fuel while still putting out as much power. The exhaust on the 4 stroke is much hotter though and this can cause problems in some cases. Also, for equivalent power, the two stroke is much less expensive.
