Roo Man,
If you are referring to the Sig Somethin Extra I would highly recommend that you forget about this plane as a second plane. I have had 3 of these planes and I will admit that they are among some of my favorite planes. They are a total blast to fly. But they are in no way suitable for somebody coming off of a trainer. This plane is a very maneuverable plane that will do a lot of things and do them quickly. It's not for somebody coming off of a trainer. Maybe as a 3rd or 4th plane, but definitely not for a second plane.
