I was only trying to be nice and not start any heat, all of what I said is true. I just was just trying not to make enemies. I am sure we have all seen the videos of the great 3d flying from the guys at 3dbatix I don't see any of them using 4 strokes. THATS WHY PEOPLE AREN'T NICE, FUNK, show a sign of weakness and you'll have someone trying to PREY on you!!!!!! I don't need to own a 4 stroke to know they are OVERPRICED JUNK, I am "SURROUNDED" by them at my flying field. And for the money I don't see anything done with a plane that has a four stroke that I couldn't do just as well if not better if I had a 2 stroke engine in the plane. IS THERE ANYONE ELSE OUT THERE WHO FEELS THIS WAY ????????
