I have the SIG kit version of this plane. It is a bit smaller with a 72 inch wing but it is about the same weight as the ARF. I fly mine with an OS 91 FS Surpass II and she flies very scale like. I have seen a lot of posting about putting BIG engines in these models to try to get them to do 3D maneuvers. These plane were not made to do that stuff. Get a 3D capable airplane if you want to do 3D stuff. Don't screw up a perfectly good scale plane...
