Speedybee TX800 5.8GHz 800mW VTX

SpeedyBee TX800 – 5.8 GHz High-Power VTX for FPV DronesThe SpeedyBee TX800 is a compact, feature-rich video transmitter (VTX) purpose-built for FPV racing and freestyle drones. With up to 800 mW of output power, a 20 × 20 mm mounting footprint and advanced control features like IRC Tramp protocol and pit-mode support, it suits serious pilots looking for strong signal performance in a light-weight package.Key Specifications & FeaturesHere’s a detailed breakdown of the TX800’s specifications and what they mean for your build:SpecificationValueFrequency & Channel Support5.8 GHz, up to 48 channels across standard bands. Oscar Liang 2speedybee.com 2Output Power LevelsPit / 25 mW / 200 mW / 400 mW / 800 mW. Oscar Liang 1Input Voltage3.7 V–5.5 V (typical use at 5 V) Oscar Liang 1Current ConsumptionAt 5 V, ~250–750 mA depending on output power. Oscar Liang5 V Output (for camera)5 V @ max 250 mA available. Oscar Liang 1Connector / Form FactorMMCX antenna connector; 28 mm × 28 mm board with 20×20 mm mounting holes (M3) and a heatsink. Weight ~5.6 g (without antenna). Oscar LiangControl ProtocolIRC Tramp VTX control supported (via flight controller/Betaflight) and push-button control as fallback. speedybee.com 1Special Feature – Pit ModeSupport for Pit Mode to reduce output power for ground checks or warm-up without interfering with other pilots. Oscar Liang 1Why the TX800 Stands Out1. High Output Power in a Compact PackageMany analog VTX modules in the 20×20 mm format are limited to lower power levels (200/400 mW). The TX800 offers up to 800 mW output, giving you improved range and penetration in cluttered environments or outdoors. Especially valuable when paired with good antenna and clean ground plane. YouTube 12. Flexible Power Levels & ControlThe ability to switch between Pit, 25 mW, 200 mW, 400 mW and 800 mW makes the TX800 adaptable for different flying contexts (indoor vs outdoor vs racing). The support for IRC Tramp protocol means you can control channel, band and power from your OSD or LUA script if your FC is configured. Manual button control provides fallback. Oscar Liang 13. Quality Build & Mounting VersatilityThe module includes a heatsink (improving thermal management), uses MMCX which is more robust than typical U.FL in many budget VTX modules, and fits standard 20×20 mounting, making it easy to integrate in micro builds or 3-4″ drones. Oscar Liang 14. Pit Mode & Smart FeaturesThe inclusion of Pit Mode is a race-day-friendly feature. It allows you to power on your bike/drone for checks with minimal interference. Combined with VTX table support and remote control via FC, this makes the TX800 smarter than basic VTXs. speedybee.comSetup & Integration GuideTo get the most from the TX800, follow these steps:Mounting & WiringAffix the VTX to your frame or stack via the 20×20 mm mounting holes (M3 screws).Ensure good airflow around the heatsink to manage heat at higher power levels.Connect power: use a regulated 5 V supply if possible (though 3.7–5.5 V range supported).Connect video input from your camera (75 Ω video impedance).Connect the antenna via the MMCX connector. Important: never power the TX800 without the antenna connected — doing so may damage the output stage. RedditFC/ESC Integration & VTX ControlOptional: Connect the TX800’s IRC Tramp pad/wire to a UART TX on your flight controller.In Betaflight Configurator > Ports tab: set the corresponding UART to type “IRC Tramp” (or similar). Oscar Liang 1Download and load the TX800 VTX table (USA/EU based on your region) from the manufacturer. Example: “SpeedyBee-TX800(USA).json”. Oscar Liang 1In Betaflight Configurator > Video Transmitter tab: enable VTX control, upload the table, make sure bands/channels/power levels match your region.Set up a mode switch for Pit Mode if needed via Betaflight Modes tab.Using the Push ButtonIf you prefer (or as backup):Short press button: change channel (1→8).Long press (2 seconds): change band.Long press (5 seconds): change power level (25mW → 200mW → 400mW → 800mW). Oscar LiangTo “unlock” higher power levels (if the LED is stuck indicating 25mW only): long press 10s to unlock. Reddit 1Thermal ConsiderationsAt higher power settings (400/800 mW) the TX800 will generate more heat. Ensure adequate airflow and keep your antenna connected. Some users have reported high core temperatures when mounted with little ventilation. RedditApplications & Best Use CasesFreestyle and racing builds: Especially useful when you need strong video signal and minimal size/weight penalty.Outdoor FPV flight: Higher power settings allow better range and penetration through trees/buildings (with a quality antenna).Micro/3-4″ drones: The 20×20 mounting and compact size make it ideal for small frames where space is limited.Club/race environments: Use of Pit Mode and regulated power levels helps you comply with club rules or reduce interference.Pros & Cons✅ ProsHigh output power up to 800 mW in a small form factor.Flexible power and channel control via IRC Tramp and push button.Lightweight (~5.6 g) and supports standard 20×20 mounting.Includes heatsink and good build quality (for the price).Pit Mode support, making it race-day friendly.⚠️ ConsAt full power (800 mW) you will need good antenna and heat management to get full benefit.Some users report firmware/Betaflight setup issues (e.g., stuck at 25 mW) if not properly configured. RedditAs an analog VTX, it doesn’t offer digital HD video—if you plan using HD systems (e.g., DJI O3/O4), you may choose a digital alternative.Output power may be limited or regulated depending on local laws—always check compliance.Final VerdictFor pilots looking for a high-power analog 5.8GHz video transmitter in a compact and lightweight format, the SpeedyBee TX800 delivers outstanding value. With full control via IRC Tramp, button backups, Pit Mode, and up to 800 mW output, it suits a wide range of FPV builds — from 3″ micro racers to full outdoor freestyle rigs. Provided you manage heat and ensure proper configuration, it’s a strong choice for serious FPV drone applications.JST socket and ———— pad connection supportedSupport IRC Tramp ProtocolTX800 supports the IRC TRAMP protocol and the modification of video transmission parameters through the remote control,Including frequency, working power and so on.
