Correct me if I am wrong, as I am not a gasser expert, but from what I have read/hear/been told inexpensive gas engines are heavy and could cause weight issues in a light plane such as an ultra stick.
The inexpensive (and yes, heavy) G-26 is a perfect fit in the Ultra stick... its like the plane was designed for it!! I certainly would not put in an aerobatic plane like and edge, extra or cap though....
