🛠️ Innovative Hybrid Construction & Factory Pre-Assembly

• High-Level Pre-Fabrication: Compared to traditional building kits, a major advantage is that almost all components are pre-assembled at the factory, except for the horizontal and vertical stabilizers, firewall, landing gear plate, and electronics. This significantly reduces your build time.
  
• Hybrid Building Technique: The structural design follows classic balsa aircraft principles. The foam skin covers an internal wooden framework, resulting in an exceptionally robust, rigid, and durable structure.
  
• Hidden Carbon Reinforcements: Carbon fiber reinforcements are embedded beneath the skin in both the fuselage and wings, ensuring maximum torsional rigidity during dynamic maneuvers and towing.
  
• Premium UV Printing: The graphics are applied using durable, highly detailed, and weather-resistant UV printing technology.

💡 Servo Mount Note: The factory servo pockets/mounts included in the kit are specially molded to fit low-profile wing servos such as the PTK 8812MG-D and Corona DS 239MG. While standard-sized servos can be installed, the factory pre-molded mounts will not fit other standard servo cases without modification.
