Somethin' Extra Model Airplane

Introduced at the 1998 National Model and Hobby Show, the new SIG SOMETHIN' EXTRAŽ was a major hit with retailers and consumers alike! The SOMETHIN' EXTRAŽ has it all; good looks, incredible performance, SIG quality balsa and ply construction and every part in the kit is laser-cut! This SIG kit can literally be built as fast as the modeler can apply CA glue and set it with accelerator.

Somethin' Extra Model Airplane

The SOMETHIN' EXTRAŽ employs a unique removable wing feature, based on an ultra-light and ultra strong tube system. This allows for super-easy building, transport and storage.
The flying capabilities of this model are virtually unlimited due to its thick airfoil section and very light wing loading. Of course, everything required to build the kit is included, right down to the great looking landing gear and wheel pants.
