The Ultasport 60 is an exceptional flying airframe
One of the very best 60 size Flyers
The 61 SF is a very good engine and it is propped right for the airframe
It is a fast performance plane that is not recommended for a beginner
You may want to restart you RC experience with a trainner and work your way into the US

I run a 91 Fx in my own and had to lengthen the tricycle gear i designed into my plane for prop clearence
The 91fx is in a 60 size crankcase that is stroked --so it is 61 engine weight-- with 91 power output !

Enjoy
