Super Skybolt Engine
K9coptx,
This plane was pretty easy to fiberglass. It was one of my first jobs and came out well.
I had a friend build one at the same time as me and cover his in monocote. He also used an OS 120 FS to power his. I couldn't feel any difference in flight characteristics between the two of them.
As to how well it flew aerobatics, I'd have to say that to an intermediate level sunday flier it flew as well as most low wing subjects you see at the field.
After programming out the roll and pitch coupling with my Futaba 7U radio, the plane handled point rolls, knife edge flight, and slow rolls very well. It'll flat spin pretty well too.
