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!
