Product Information

Years of F3A and 3D biplane experience give Quique Somenzini the knowledge to design the Mamba to fly just right. Starting with a Model 12 that is officially licensed from Jim Kimball Enterprises, Quique made a variety of changes to improve and perfect the Mamba 120 as a 3D aerobatic model.

The Flex Innovations Mamba 120 excels in light wing loading and absolute minimum control coupling that are important in providing exceptional 3D performance.
