Product Information

Experience 3D flying like you never have before

With attention to aerodynamic and geometric detail like no other, the Flex Mamba lets you tackle any turn or trick your heart desires.

Its large wingspan and fiberglass wheel pants and new cowling gives you agility – and its precise aerobatics helps you always stay in control.

Added wing chord, new wing tips and ailerons

New features have been added to the Flex Mamba, including new cowling, additional wing chord and updated wing tips and ailerons.

Its main hatch and auxiliary forward hatch can be taken off easily, without tools! And there’s the option to add Shark Teeth Leading edge to reduce Wing Rock and gain control at lower speeds.

With years of F3A and 3D biplane experience, the designers of the Mamba offer features that are not only new to Flex Innovations, but are new to the market too.
