The model is designed for competitive flying in the F3L and RCVS categories. The wing and tail surfaces are built-up structures, and the wing spar is reinforced with carbon fibers. The covering is made from Oralight heat-shrink film.

The model has excellent flight characteristics in all weather conditions. Thanks to the ballast system, it can be flown in wind speeds of up to 5 m/s.

The fuselage features a plywood pod with a carbon boom extending to the rear. An adjustable tow hook is mounted under the fuselage, allowing precise trim adjustment for any weather conditions.

The horizontal stabilizer is mounted on a pylon and secured with two 3 mm plastic screws.

Dex has an extended lower section of the vertical stabilizer below the tail boom. Thanks to this, it responds immediately to control inputs, and turns can be flown with a high bank angle without sinking or losing speed.

The wing features a center-mounted air brake. Ballast for increasing the model’s weight in stronger winds is placed under the wing between two bulkheads.

The wing chord at the root is 210 mm.
The model weighs approximately 450 g.
