RATE O4 Upgrade Set 145° FOV Wide Angle Lens 7g ultra-light CNC full-cover heat dissipation protective case for DJI O4 lite FPV racing Drones

Heat Is the Enemy of Speed Here's what they don't tell you about digital FPV systems: when your VTX overheats, it doesn't just get hot—it throttles. Power drops. Signal weakens. Latency creeps in. aAnd in the middle of a race or a long-range mission, that's the difference between first place and a walk of shame. The RATE O4 CNC Aluminum Housing was engineered to kill this problem at the source. From Plastic to Precision Aluminum Stock plastic enclosures trap heat. Aluminum dissipates it. The RATE O4 replaces your factory shell with a precision CNC-machined aluminum alloy housing that acts as a massive passive heatsink. It pulls thermal energy away from your VTX module and radiates it into the airflow. The open-frame structure amplifies this effect—over 30% improvement in cooling efficiency compared to sealed plastic shells. No fans. No added power draw. Just physics doing what physics does best. 7 Grams. Zero Compromises. Lightweight enough for toothpicks. Rugged enough for 5-inch freestyle. At just 7 grams including screws and pads, the RATE O4 adds virtually no penalty to your build. Yet it brings dual mounting pattern support (20×20mm and 25.5×25.5mm M2/M3 slots) for near-universal frame compatibility. Vibration-resistant mounting keeps everything locked down through hard crashes and resonant frequencies that shake lesser housings loose. The Full Ecosystem – One Kit, All Options Don't piece together your upgrade from five different listings. The RATE O4 Full Accessory Kit bundles every component into one package: - The CNC aluminum housing (the core upgrade) - Extended lens housing (20mm wide-angle compatible) - Extended coaxial cable (clean antenna routing) - 6-pin ribbon cable (100mm, plug-and-play connectivity) - Multiple antenna options (Black or Transparent) - Choose the variant that matches your build. One purchase. Everything you need. Features * CNC-MACHINED ALUMINUM ALLOY: Precision-cut from solid aluminum. Functions as a passive heatsink, wicking heat away from VTX modules to prevent thermal throttling and signal degradation. * 7 GRAMS TOTAL WEIGHT: Including screws and mounting pads. Featherweight design adds zero perceptible payload to race or long-range builds. * 30%+ AIRFLOW IMPROVEMENT: Open-frame structure dramatically increases air circulation around the VTX compared to sealed plastic enclosures. Sustained high-power transmission without thermal dropout. * DUAL MOUNTING PATTERNS: Compatible with both 20×20mm and 25.5×25.5mm frame layouts via M2/M3 vibration-resistant screw slots. Fits most racing, freestyle, and cinewhoop frames. * FULL ACCESSORY KIT OPTION: Includes CNC housing, extended lens housing (20mm), extended coaxial cable, and 6-pin ribbon cable. Antenna available in Black or Transparent. * WIDE VTX COMPATIBILITY: Optimized internal layout fits DJI O4 Air Unit, TBS, Rush, and other mainstream VTX modules. * QUALITY UPGRADED MATERIALS: Selected injection-molded components enhance structural stability, durability, and fit precision while maintaining the ultralight profile.
