FlySpark 1.2G / 1.3G Long-Range FPV VTX Series | 2W, 4.5W & 5.5W Analog Video Transmitter Modules

Key facts

At a glance

The FlySpark 1.2G / 1.3G Long-Range FPV VTX Series is a set of three analog video transmitter modules (2 W VTX-F3, 4.5 W SK-VTX05 and 5.5 W VTX-F11) for long-range FPV drones, fixed-wing UAVs and inspection or test platforms. All three take 7–36 V DC input, provide a 5 V output, support IRC control with OSD parameter adjustment and PIT mode, and cover up to 1080–1360 MHz. Listed prices run from US$131 to US$269

Use cases

• Long-range analog FPV video downlinks on multirotor and fixed-wing drones
• Surveillance and inspection UAV video links
• UAV test platforms and custom drone builds needing a 1.2–1.3 GHz video link

Standards & references

• ITU Radio Regulations — The 1080–1360 MHz coverage spans several internationally allocated services, so permitted channels and power vary by country.
• DoT Wireless Planning & Coordination (WPC) Wing, India — The catalog requires use only on frequencies and power levels permitted under WPC/DoT spectrum rules; transmitting outside them needs WPC authorisation.
• GPS technical references (U.S. Coast Guard Navigation Center) — The GPS L2 (1227.60 MHz) and L5 (1176.45 MHz) signals fall inside the 1080–1360 MHz coverage, so channel choice should avoid degrading on-board GNSS reception.

Intelligence Brief

Mission overview

FlySpark 1.2G / 1.3G Long-Range FPV VTX Series | 2W, 4.5W & 5.5W Analog Video Transmitter Modules

The FlySpark 1.2G / 1.3G Long-Range FPV VTX Series is designed for FPV drones, long-range UAV platforms, fixed-wing drones, surveillance drones, inspection UAVs, testing platforms and custom drone builds that require stable analog video transmission in the 1.2GHz / 1.3GHz frequency class. This series includes multiple output-power options, allowing users to select the correct VTX based on range requirement, power budget, antenna configuration, mounting space and mission profile.

The series includes three variants: VTX-F3 2W, SK-VTX05 4.5W and VTX-F11 5.5W. All variants support IRC control protocol and OSD parameter adjustment, allowing convenient configuration through supported flight-controller / OSD workflows. These modules support wide DC input power from 7V to 36V and provide DC 5V output, making them suitable for multiple UAV power-system layouts.

The 2W VTX-F3 is a compact 30.5mm mounting option with MMCX antenna connector. The 4.5W SK-VTX05 and 5.5W VTX-F11 are higher-power modules with SMA antenna interface and 20×20mm mounting pattern.

• AVAILABLE VARIANTS:
• • 1.2G 2W VTX-F3 — US$131
• • 1.2G / 1.3G 4.5W SK-VTX05 — US$221
• • 1.2G 5.5W VTX-F11 — US$269

IMPORTANT USE NOTE: This product is an RF video transmitter module. Use only on legally permitted frequencies, power levels and operating locations. Users must follow WPC/DoT/local spectrum regulations, aviation rules, site permissions, RF safety requirements and lawful drone operation practices. Antenna must be connected before powering the VTX to avoid RF power-stage damage.
