• True‑to‑scale, rugged design：1:36 EC135 replica with high‑fidelity injection‑molded fuselage, CNC rotor head and swashplate, plus nylon/carbon‑fiber composites for strength, resilience and impact resistance.
• Coaxial powertrain & stabilization： Dual‑axis coaxial brushless motors (2507 1300KV main, 1204 7000KV tail) with heat‑resistant magnets; 6‑axis gyro and optimized structure provide precise electronic stabilization and reduced damage risk.
• High‑performance flight controls：Three oversized 4.3 g digital servos (60°/0.05 ms) delivering high torque, fast response and pinpoint centering; maintains accuracy even in 4–5 level winds over 2.4 GHz link.
• Smart positioning & altitude hold：Downward optical‑flow sensor for indoor hover; green LED indicates locked altitude (≤ 8 m), red LED outdoor manual hold; simple button/joystick override for higher flight.
• Long‑life battery with safety features： Custom 7.4 V 1200 mAh 25 C LiPo (≈ 8–9 min flight),> 500 cycles; integrated over‑charge/discharge protection, low‑voltage alerts and USB‑C charging.
