I. Key Specifications: Engineered for Performance

The Nightingale X5 is a classic DC-style racing frame. Its core data reflects a clear philosophy of optimization for flight:

• Dimensions & Weight: Compact at 230mm × 220mm × 57.5mm (L x W x H) with a net weight of just 248 grams, providing an excellent foundation for agile handling.
  
  

• Wheelbase: 228mm, perfectly matched for 5-inch propellers, balancing agility and stability.
  
  

• Motor Compatibility: Supports popular 2207 and 2306 motor sizes with a 16mm bolt pattern.

• Electronics Compatibility:

  • Flight Stack: Supports the standard 45×45mm mounting pattern with adjustable hole spacing from 20-30.5mm.

  • Video Transmitter (VTX): A dedicated 40×36mm area accommodates most micro HD VTX units.
    

  • Camera: Supports 20mm standard cameras with both 6mm and 16mm hole spacing options for flexibility.

• Power Recommendation: Designed for 1450-1650mAh 4S-6S LiPo batteries, optimizing the balance between power and flight time.

II. Design Details & Assembly Experience: Thoughtful & Practical

1. Modularity & Repair-Friendliness

The frame uses a split design, separating the bottom plate from the side arms. This not only reduces weight but significantly lowers repair costs after a crash—you only need to replace the damaged component, not the entire frame.

2. Unique Optical Fiber LED Lighting System

A standout feature is the integrated LED board with an optical fiber light guide system. The manual cautions against using sharp tools during installation to avoid damaging the fibers and suggests leaving about 0.5mm of extra fiber at the LED end for optimal light diffusion and brightness. This system greatly enhances visibility and orientation during night or low-light flights.

3. Clear Assembly Instructions

The manual is bilingual (Chinese/English) with illustrations for key steps. For example, it clearly warns to protect the surrounding LEDs when installing the receiver antenna mount. While complete beginners might face a learning curve, the process is intuitive and straightforward for builders with basic experience.

4. Attention to Compatibility

The manual specifically notes that "left and right accessories are not interchangeable." This professional detail prevents installation errors and rework, highlighting the frame's thoughtful design.

III. Expected Flight Performance Analysis

Based on its structural design and feedback from similar products, the Nightingale X5's flight characteristics are anticipated to be:

• Agility & Responsiveness: The lightweight frame promises a high thrust-to-weight ratio and instant control response, ideal for racing and aggressive freestyle maneuvers.

• Structural Rigidity: The intelligent load distribution and robust mounting points should withstand the stresses of high-speed impacts and sharp turns.

• Airflow & Efficiency: The compact layout helps minimize turbulent airflow, potentially improving flight efficiency and battery life.
