Designed with advanced aerodynamics, reinforced drivetrain components, and improved vibration control, the RS7 ULTRA delivers precise flight characteristics for demanding pilots.

Note: This kit does not include main or tail blades.

✔ Low-Drag Aerodynamic Design
Optimized airflow management using ridge-line canopy shaping, dual-curvature air ducts, and vortex-reducing edges. Improves cooling efficiency while reducing drag for enhanced stability.

✔ Reinforced Main Gear System
Larger diameter main gear with optimized helical angle improves transmission efficiency and torque delivery.

✔ Adaptive Belt Tensioner
Adjustable dual-shaft tensioner system with precision CNC construction ensures consistent belt performance and reliability.

✔ Advanced Shock Absorption
Enhanced vibration damping system reduces gyro interference for more precise and stable flight control.

✔ Optimized Tail Assembly
Lightweight redesign reduces weight and vibration while improving tail response and control authority.
