I. XLPower Stratos 200 Helicopter Kit with Azure Power Blades:
1. Introduce:
Meet XLPower’s new 200-class helicopter, engineered to deliver the feel of a larger machine in a compact, ultra-efficient package. Borrowing true 1:1 rotor geometry and control concepts from our 700-class platform, it delivers smooth, linear response with confident control. First in its class, an adjustable battery system unlocks true 4S performance. Factory-calibrated and built with an integrated motor and ESC drivetrain(Hobbywing Platinum V5 ESC), it features a clean, telemetry-ready electronics layout for a streamlined setup. A rapid service tail system ensures that even after a crash, repairs are quick and hassle-free, with no wiring or soldering required. Compact, performance-driven, and easy to maintain, it’s a micro helicopter that flies precise, responsive, and seriously fun.
