Feature 5



The SIG Somethin' Extra is a stunning and agile high-performance R/C plane. It boasts SIG legendary performance and craftsmanship, along with modern styling. This plane is guaranteed to stop people in their tracks - both on the ground and in the sky.

Just like its name implies, this kit will provide you with “SOMETHING EXTRA.” The unique removable wing-panel feature makes this possible because it uses an ultra-light and strong tube system. Additionally, you will find that the thick airfoil section and light wing loading give this model broad flying capabilities. To top it off, it is a plane that will assemble, store and transport easily to your flying field.

That is just part of the reason why this plane is a hit with discriminating RC pilots. Add in the visual appeal of the landing gear and overall design, the precision-molded wheel pants, crystal-clear canopy, quality balsa and plywood construction, and of course, the laser-cut parts for precision fit and ease in building. Plus, this SIG kit is a real performer in the air. It is an ideal plane choice for club contests!

Great Plane, Love It!
Like any other kit, this does not come with covering or paint, or even all of the hardware... it comes with a pretty generous amount however compared to some offerings by other companies. The kit goes together really easy in a few nights if you are a fast builder. The plane flies so smooth and does just about anything you ask it to. Great kit, great flying plane, I recommend it to everyone.
