The concept:

Felix Rodriguez’s Pro Model. Designed by Dav Dagault with constant feedback from Felix, the goal of the FLX.3 is the same as each of the two previous versions: maximum acro with maximum ease, comfort, and precision

New Features:

The FLX.3 is an evolution of the FLX.2
A new profile has been used in order to get the pitch speed of the FLX2, but with increased fluidity and comfort, which translates to increased ease of use.
A new plastic leading edge reinforcement ensures the longevity of the most important part of the wing.
A new tension strap arrangement with refined lengths has been implemented, for easier infinite tumbling.
The FLX.3 remains one of the most durable wings ever built with internal reinforcement and extremely high resistance to the inevitable wear and tear of serious acro flying.
