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.
2. Features:

2.6. Factory Pre-Calibrated Setup
Servos are factory-centered and the swashplate is perfectly leveled right out of the box. This eliminates complex setup after assembly and reduces build time significantly. The result is a smoother, more approachable experience for pilots of all skill levels.
2.7. Integrated Power and Frame Structure
The integrated power and frame structure combines the main shaft block, center frame, and motor mount into one rigid, compact drivetrain. A gearless drive design eliminates gear mesh and concentricity issues, delivering smoother and more efficient power. The quick-change main shaft allows fast maintenance without removing surrounding components, getting you back in the air sooner.

Supports 3S to 4S setups
Maximum battery size: 24mm × 32mm × 70mm
2.10. Ultra-Stable Landing Gear
Extra-wide and low landing gear delivers rock-solid stability during takeoff and ground handling. The planted stance prevents forward tipping and gives the helicopter a performance stance and controlled presence on the ground.
2.11. Beginner-Friendly Tail Layout
The top-mounted tail motor protects the tail blades from ground strikes, delivering safer, cleaner takeoffs and landings while keeping the tail protected where it matters most.
Safer and more forgiving for beginners
Cleaner, more protected tail assembly
2.12. Fast-Service Tail System
The fast-service tail system is engineered for maximum simplicity and speed, featuring a plug-in tail boom with built-in gold connectors for quick removal and installation. An integrated PCB swash guide and servo-style tail ESC eliminate wiring, routing, and soldering, making adjustments fast and frustration-free. The result is a true rapid service design that gets you back in the air in minutes.
