RADICAL4
Freestyle, Freeride
The Radical4 lives up to its name. This board line is even sportier than its predecessor and features a perfect mix of materials, an asymmetric outline and the proven elliptical concave.

Features
WOOD-FOAM CORE
RADICAL5’s have a hybrid core, achieving perfect harmony of board weight, performance and durability. A foam core is used on the toe-side in the longitudinal direction, providing a significant reduction in board weight. In the heel-side that is under more force and load, a robust wood core is used. Guaranteeing dynamic recovery force of the board, while retaining huge amounts of strength.
Torision Fiber Layers
The innovative assembly of a unidirectional woven layer lengthwise and an additional diagonal layer (torsion layer) at a 45-degree-angle achieves considerably more recovery force, which is reflected in the increased jump performance. Still, the flex of the board is tuned so harmoniously that comfort and smooth ride are not negatively influenced.
Pad-Strap-Combo
The Radical4 has an easy-adjustable velcro footstrap system on it. These footstraps have a perfect and comfortable fit and offer optimal foothold. The enormous adjustment range goes from shoe size 38 (barefoot) to shoe size 48 (with neoprene boots).
Tucked-under Edge
The „Tucked-Under“ Edge has been cut off at a 45-degree-angle, as surfboards have been traditionally manufactured. This makes the board well-controllable, even in choppy conditions.
Additional Grabrails
The additional Grabrails are absolutely soft, but still offer the best control for board-offs or one-footers. Thus, holding the board has become much easier. The Grabrails can easily be glued to the deck.
UV- and scratch-resistant Deck Coating
All of our boards have a special high-quality UV- and scratch-resistant coating, and thus offer a long product life. The design is protected under the coating, so that it does not get damaged if the board is slightly scratched.
Ergonomic Toaside Outline
The asymmetrical rounder and shorter toeside outline increases control when riding toeside and provides increased comfort.
Wider Insert Position
Wider Insert Positions make it easier to land. There are three different stance options possible – Small (50.4 cm), Normal (56.2 cm) and Wide (61.2 cm).
Heelside Channel
The deep Heelside Channel provides good grip and makes it possible to set the edge more effectively for jumping.
RADICAL … even sportier!
The Flyboards-Development team surrounding Andreas Hanrieder and Eddy Lansink did an excellent job, optimizing the Radical4 in practically all regards. The first priority was the switch in production center from Asia to Europe, which led to a higher quality of workmanship. Once this was implemented, a stronger differentiation of the range could be undertaken, whereby each board was tuned individually to riding weight and range of use.
All Radical4s have a hybrid core, aimed at achieving a maximum harmony of board weight, performance and durability. A foam core is implemented on the toe side lengthwise, providing a significant reduction in weight. In size M, the Radical4 weighs 2,3 kg, bringing 20% less to the scale than its predecessor. The new production process also plays a considerable role, whereby a higher pressure is used in the molding press of the resin content with simultaneous increase of glass fiber content, responsible for the flex properties and durability. On the side with more load, the heel side, a robust wood core has been implemented, guaranteeing break stability and the dynamic recovery force of the board.
