RATE designs for racers who push limits The O4 housing was born from a simple truth overheating VTXs fail when you need them most We used precision CNC aluminum to create a shell that acts like a heat sink dissipating thermal buildup reducing throttling and extending module life No extra weight no weak points just cleaner signal and relentless performance Because winning happens at full throttle Feature CNC machined aluminum alloy housing for maximum heat dissipation Ultra lightweight design only 7 grams Optimized internal layout fits most standard VTX modules e g TBS DJI Rush Secure mounting with vibration resistant M2 M3 screw slots Open frame structure improves airflow and cooling efficiency by over 30 Specifications Brand RATEModel O4 CNC Aluminium HousingMaterial CNC Aluminum AlloyWeight 7g including screws pads Dimensions 30 5mm 30 5mmO4 Heatsink w Screws 6 9g 31 4 31 4 8 9mm Mounting holes 20 20mm and 25 5 25 5mm20mm Wide Angle Lens Lens 5 9g 22 8 20 22 7mm Coaxial Cable 0 8g 150 13 5 1 54mm 6 Pin Ribbon Cable 1g 108 8 9 2 73mm Package Included 1x O4 Video Transmission Antenna Black or 1x O4 Video Transmission Antenna Transparent or 1x O4 Extended Lens Housing 20mm or 1x Extended Coaxial Cableor 1x 6P Connecting Cable 100mm or 1x O4 Lightweight CNC Housing 7 0g or 1x Large Camera Extended CNC Kit Includes all accessories only one antenna
