It's not anything like A trainer just because the wing is on top. It's A high wing stunt plane, I love them. I had the Decathlon and loved it. I still keep thinking about another one in my hanger too. I always show my students the plane as A second plane when they start getting into stunt flying.
As I recall mine was A GP kit though??? Been A while. Sorry, I can't say anything about the SIG kit but I can't remember building there Cit. Still, it's A SIG and I haven't found A bad one yet, just more sanding thennI like to do.
