Now I am getting picky. I had a bad experience with Super Tigre engines. Hard to tune and flame outs. Don't know if I had a lemon or how to tune, But that one engine turned me off on super tigre engines. I am wanting to know if a .61 2s is a = to a .91 4s on this plane or do I need a bigger 2s like a .75 or .90 2s.

I am mostly just a sport flier and that is what this plane will be used as. Just something a little more "snappy" to take to the field when I am in the mood.
