I have a Sig Kougar with a Rossi 60 on the front. It will take off at half throttle and really move. The airframe was built on the heavy side and adding the 60 was not one of my best ideas. Made the plane just over the MAX that Sig recommends. The plane to begin with has a tendency to snap when going to slow and to much elevator has been added. I found out the hard way on landing.

I would recommend sticking with in the 40-50 size engine range. Unless you are going to go with a Jett. Or you airframe has been built LIGHT.
