Second Plane?
Evening Whirley Bird,the Koas is an old style kind of pattern plane,basically designed to fly on the wing,and it's a good weekend flying plane,with enough engine one can make a cub have unlimited vertical.Don't known what you are looking for or how much experience you have.If you have three to five models up on the learning scale,and the Pitts turns you on, go for it,I prefer the Ultimate but each to there own,a single wing I like the 300's,these types of planes are designed more for the sure nuff out and out wild flying.
