Both are EXCELLENT airplanes. I have both, and I love them....as far as which one flies better.....well.......I can't say! The tiger 2 is a heavier plane, so it requires a good, ball-bearing .46-.51 engine to get the best of it......the Four Star is lighter (at least the kit-built one, which I have, is lighter), so a lower-cost bushing .46 might fly it well. (I would still recommend a ball-bearing .46 for it).

The four star is a taildragger....and the Tiger 2 is a trike gear, with the option to change it to a taildragger, so the Four Star will take a little more effort on the ground.

The Tiger 2 definitely handles wind better....in fact, the Tiger 2 and my Ultra Stick .40 are the planes I prefer to fly on windy days.

The Four Star is a real floater, and flies very "lightly" with a Ball Bearing .46

Like I said.....I can't tell you which flies better.....I don't think there is an answer to that question.....but these are the major differences that I've noticed.
