I just got back from a swap meet this weekend and got rid of my last 2 stroke! The last 2 were cheap chinese 2 strokes that didn't make that much power or run that good. The new Saito that replaced them is ready to start the break in the next warm afternoon. For my type of flying 3d and everyday sport flying the 4 strokes suit me better. I won't say I will never buy another 2 stoke but it will only be for cheap combat planes or fast pylon racers.
