Features:
1> Low-Drag Aerodynamic Canopy: Streamlined ridges and air ducts reduce drag and boost cooling efficiency, ensuring smoother, more stable flight performance.
2> Main Gear Reinforcement: Larger helical gear design improves torque output and transmission efficiency, optimized for demanding 3D flight maneuvers.
3> Adaptive Tensioner Wheel: Fully automated system compensates for belt changes, maintaining peak transmission efficiency during high-intensity use.
4> Tail Assembly Optimization: Lightweight tail reduces weight by 8g, increased response speed, and vibration control for precision performance.
5> Enhanced Shock Absorption: Advanced vibration filtering ensures gyroscope precision and aircraft stability even during aggressive maneuvers.
