I also had a 60 sized one as my second plane. I only had an OS 70 four stroke on it, but I loved it. As a second plane, it did everything I wanted it to do. I've always wondered what it would be like with flaps and a stronger engine. I also like the rounded tail on it. I don't know if the Ultra Stick's angled tail improves it's aerodynamics; but I prefer the appearance of the rounded tail. Just my opinion.
