Zefixx, Grüner CNC, Mini Hotliner, Span 1470mm, Laser-cut kit

Construction Manual

ZEFIXX Decal as .dxf

The Zefixx is a high-quality wooden kit for ambitious model aircraft enthusiasts who value precise construction, excellent flight characteristics, and clean build execution. With a wingspan of 1,470 mm and its one-piece, fully sheeted wing, the model impresses with high stability and very good handling.

The wing is constructed with a ribbed structure and completely sheeted with 0.4 mm plywood. This results in a torsionally stiff and robust structure that allows for both smooth gliding and dynamic flight maneuvers. The Zefixx is controlled via ailerons and elevator, with the option of additionally connecting a rudder. This optional rudder linkage allows for extended flight control and is already fully included in the kit.

High-quality kit in proven Grüner quality

The kit meets the well-known Grüner quality standard and contains precisely CNC-laser-cut parts that enable quick and precise assembly. A multi-color construction plan and a richly illustrated, German-language construction manual guide you safely through all construction steps – ideal for experienced model builders as well as advanced beginners in wooden model building.

Solid construction and well-thought-out details

The fuselage is made of carefully selected balsa wood and constructed with plywood bulkheads dovetailed into the side walls. In the wing seating area, the fuselage has been generously reinforced with light plywood to permanently absorb the forces acting there.
A pre-milled nose block is already prepared and allows for easy and clean mounting of the intended electric drive.

The tailplane is designed as stable plates and harmoniously integrates into the clear, functional design of the model.

The one-piece wing is built on the lower sheeting using a main spar, ensuring exact airfoil fidelity. Matching plywood servo frames for installing the wing servos are included in the scope of delivery.
