I just finished building a King Kobra, and although it wasn't the easiest kit in the world to build, Sig kits are never-the-less great flying planes. You get what you put into it. I put together an ARF last year to have something quick to fly, but the sense of satisfaction was no where near what I feel with this plane ever time I look at it. Actually building a plane and watching it fly is one of the greatest feelings in the world, and can never be matched by "building" and ARF. If you want quick, build an ARF, if you want real enjoyment and a sense of accomplishment, build a plane from a kit. I attached a pic of my finished plane.
