The Pichler Model C6563 retractable landing gear is designed for use in model airplanes that require precise landing gear functionality. This landing gear system features a fully retractable design with smooth mechanical operation and is made from durable aluminum alloys and high-quality steel components for reliable performance. The landing gear measures approximately 150 mm in length when extended, with a retracted height of 45 mm, and supports aircraft models weighing up to 2.5 kg. It includes integrated shock absorption with a 15 mm spring travel for effective landing impact absorption. The system operates on 4.8-6 V DC with a current consumption of 800 mA and features ball-bearing wheels with a diameter of 40 mm and rubber tires for optimal ground handling. Installation requires a mounting area of 60 x 40 mm, with standard M3 fasteners included. The landing gear mechanism ensures consistent extension and retraction cycles with position feedback for precise control integration. All moving components are precision-engineered for smooth operation and long-term reliability. The design allows for standard servo connections with 3-pin connectors for easy integration into most radio control systems. This landing gear is suitable for model scales from 1:10 to 1:8, particularly for warbird and sport aircraft applications where authentic retractable landing gear functionality is required. The construction uses corrosion-resistant materials throughout, with all electrical components designed for continuous operation under typical modeling environments. The system includes pre-assembled wiring harnesses of suitable length for most aircraft installations. This landing gear represents the successor to earlier C-series designs, featuring improved mechanical efficiency and enhanced durability characteristics.
