Our 1.2/1.3, 4.9 and 5.8GHz products, plus wide-band and higher-frequency options, provide choices for sourcing around existing receiving equipment.
The 5.8GHz 1.6W and 3W transmitters offer different intermediate outputs, giving your assembly more choice than maximum wattage alone.
The two 5.8GHz models weigh 15.8g and 16g. Their dimensions let you compare output against available space and mass.
We quote against your requirements and quantity, then confirm configuration and delivery terms with you before arranging supply.
FPV Video Transmitters for Platform Assembly and Supply
Xingkai’s VTX for FPV range serves businesses developing, assembling or sourcing FPV equipment. It includes 1.2/1.3, 4.9 and 5.8GHz products, a 4.9–6.1GHz option, 7.2GHz and 8.5GHz products, and 10W transmitters.
Product-specific power settings, antenna connections and dimensions help you choose a transmitter to suit your receiver and platform. For 5.8GHz assemblies, the 1.6W model offers a lower profile, while the 3W model provides higher output settings with a heatsink and cooling fan.
Tell us your configuration requirements and quantity. Xingkai checks the product and configuration details and provides a quote. Once both sides confirm the configuration, quantity and delivery terms, we arrange supply and dispatch according to the confirmed order.

Match Your Analog VTX to the Receiving System
An analog VTX needs a compatible analog video path and a receiver tuned to the required channel frequency. Match the actual transmitter and receiver frequencies; a shared band name or overlapping frequency range alone does not establish a channel match. For digital HD video and data requirements, explore HD Video Data Links.
For a receiver-matching enquiry, include the receiver model or frequency table and camera output details, where available.
Fit the VTX to Your Platform
The six transmitter configurations in the specification table accept 7–36V DC input. Current requirements still vary with the product and output setting: the 5.8GHz 1.6W model specifies 620mA at 12V when transmitting at 1600mW. PIT marks a low-power mode for setup on the products that list this function.
View full-size imageThe 1.2GHz 800mW option measures 45.5 × 35.6 × 11.5mm and weighs 21g. The 1.2/1.3GHz 2W option measures 37.7 × 36.1 × 11mm and weighs 16g. Both use 30.5 × 30.5mm mounting, but their different bodies matter when allocating space around other components.
View full-size imageThe 1.2GHz 800mW and 1.6W options use SMA connections; the 1.2/1.3GHz 2W, 4.9GHz 1.6W and two featured 5.8GHz models use MMCX. Antenna connection and flight-controller control are separate configuration questions. For controller-based setup, identify the controller and firmware version; the antenna connector alone does not establish control compatibility.
View full-size imageThe 5.8GHz 3W transmitter uses an aluminium heatsink and fan. The SpiderRC 4.9–6.1GHz 3W option also combines an aluminium housing with a cooling fan. These structures help you plan the installation around active cooling; space for the assembly and an airflow path remain part of the platform layout.

FAQs: FPV VTX Procurement Questions
No. The VTX options here are for FPV video transmission, which is separate from the radio-control link used to operate the platform. If you also need control transmitters or receivers, identify them separately in the enquiry. Our FPV Accessories range covers related equipment.
Use a table matched to the specific transmitter and its supported control method. Betaflight’s documentation separates frequencies and power settings from hardware-specific control values. For a Betaflight-based build, identify the chosen VTX, flight controller and firmware version. The antenna connector or maximum power rating alone does not establish control compatibility.
Output wattage alone does not establish a guaranteed transmission distance. Receiving equipment, antenna arrangement and operating conditions also matter. Describe your required distance and use conditions alongside the receiver, antenna and platform details. The complete installation needs validation under your intended operating conditions.
Send the original VTX model, its operating settings and the receiving equipment used, together with a description of when the video was lost. A video outage can involve the camera or other parts of the signal path, so a replacement request should identify the existing configuration. Xingkai uses these details to check the requested replacement product and provide a quote.
Continue Your FPV System Sourcing
Explore receivers, antennas and viewing equipment for an FPV system. Pairing and package contents depend on the selected products.
Consider this range when your project needs digital video and data transmission beyond the FPV video transmitters featured here.
Review camera and payload options for your platform; video output and transmitter compatibility depend on the specific configuration.
Explore portable control and viewing equipment when the project requires a broader ground-side operating arrangement.
Discuss Your VTX for FPV Requirements
Tell us the transmitter option and quantity you are considering, or describe your platform requirements if you have not chosen a product. Receiver information, camera output details, power supply and installation limits help Xingkai check the configuration where relevant.
If you also need video receivers, antennas or cables, list these items and their quantities separately.
We respond with product and configuration information and a quote. Configuration, quantity and delivery terms are confirmed with you before we arrange supply and dispatch.
