4 Inch Reinforced T700 Carbon Frame Kit 173mm Wheelbase 55g Lightweight Structure 3.5mm Thick Arm Mechanical Propulsion Component (1 Set)(Frame Kit)

The Reinforced 4-Inch LR Series Frame is a professional structural solution engineered for high-efficiency micro-mechanical power systems. By combining 3.5mm reinforced arms, T700 high-modulus carbon , and CNC aluminum side plates, it delivers exceptional structural durability for demanding environments at a minimal weight. This set is ideal for repair applications requiring strict payload efficiency, clear visual observation, and component integration.Technical Specifications:- Model: 4-Inch LR Series (Reinforced Lightweight Frame)- Material: T700 Carbon / 4mm CNC Aluminum - Geometry: Deadcat (Prop-free view design)- Wheelbase: 173 mm (Motor to Motor)- Thickness: Arm 3.5mm / Plates 1.5mm- Spacing: 19mm / 20mm compatible- Mounting Patterns: 20*20mm / 25.5*25.5mm (M2)- Motor Patterns: 9*9mm / 12*12mm (M2)- Total Weight: Approximately 55.6g (including TPU)- Target Audience: Users aged 14+Package Included:- 1 x Reinforced Carbon 4-Inch Frame Assembly (with CNC side plates)- 1 x Complete TPU Protective Kit (including arm protectors and mounts)

• Sub-250g Lightweight Logic: This 173mm wheelbase frame is specifically engineered for lightweight power systems, weighing only approx. 55.6g with all TPU parts. This specification minimizes operational inertia, making it an ideal core architecture for building sub-250g mechanical platforms.
• Deadcat Layout Consistency: Utilizes a Deadcat geometric layout designed for an unobstructed physical field of view. Paired with CNC 4mm aluminum side plates and absorbers, it effectively isolates physical vibrations to ensure mechanical consistency for optics.
• Reinforced 3.5mm Structural Arms: Arms are crafted from 3.5mm reinforced T700 carbon plates, providing robust physical support and superior fatigue resistance. The hardware set includes 12.9-grade strength bolts pre-applied with thread locker for enhanced mechanical stability.
• Integrated Interface Solution: The top plate and rear section feature integrated mounting positions for power connectors, allowing for a flush physical layout of wiring. A dedicated capacitor cutout is also included to ensure tidy arrangement of electronic components within the compact frame.
• Versatile Component Compatibility: Supports 25.5x25.5mm and 20x20mm mounting patterns and is compatible with 19mm/20mm formats. The complete TPU kit includes arm protectors and mounts, meeting the repair requirements for users aged 14 and above.
