FlySpark 1.7G Long-Range FPV VTX Series | 4.5W & 6W Analog Video Transmitter Modules | 1680MHz–1960MHz

Key facts

At a glance

The FlySpark 1.7G Long-Range FPV VTX Series has two analog video transmitter modules for FPV drones and fixed-wing UAVs: the 6 W VTX-F9 (8 channels) and the 4.5 W SK-VTX06 (16 channels). Both cover 1680–1960 MHz, run from 7–36 V DC, use SMA antenna connectors and support IRC control, OSD parameter adjustment and PIT mode. Listed prices are A$353 (VTX-F9) and A$357 (SK-VTX06).

Use cases

• Long-range analog FPV video on multirotor and fixed-wing UAVs
• Inspection and surveillance drone video links
• UAV test systems and custom drone builds needing a 1.7–1.9 GHz video link

Standards & references

• ITU Radio Regulations — The 1680–1960 MHz range overlaps bands allocated internationally to other services, so usable channels and power differ by country.
• DoT Wireless Planning & Coordination (WPC) Wing, India — The catalog requires operation only on WPC/DoT-permitted frequencies and power levels; anything else needs WPC authorisation.

Intelligence Brief

Mission overview

FlySpark 1.7G Long-Range FPV VTX Series | 4.5W & 6W Analog Video Transmitter Modules

The FlySpark 1.7G Long-Range FPV VTX Series is designed for FPV drones, fixed-wing UAVs, long-range drone platforms, inspection UAVs, surveillance drones, testing systems and custom unmanned aircraft builds that require powerful analog video transmission in the 1680MHz–1960MHz frequency range. This series is available in 4.5W and 6W output-power variants, allowing drone builders to select the correct VTX according to range requirement, antenna setup, available mounting space, thermal management and power-system design.

The series includes two main variants: 1.7G 4.5W SK-VTX06 and 1.7G 6W VTX-F9. Both variants support IRC control protocol and OSD parameter adjustment, making configuration easier through supported FPV/OSD workflows. Both modules support DC 7V–36V wide input voltage, DC 5V output voltage, SMA antenna interface and PIT Mode for safe low-power setup.

The SK-VTX06 is a 4.5W 16-channel VTX with 20×20mm M2 mounting, suitable for compact high-power builds requiring more channel flexibility. The VTX-F9 is a 6W 8-channel VTX with 30.5×30.5mm M3 mounting, suitable for users who need maximum listed RF output power in the 1.7G VTX class.

• AVAILABLE VARIANTS:
• • 1.7G 6W VTX-F9 — A$353
• • 1.7G 4.5W SK-VTX06 — A$357

IMPORTANT USE NOTE: This product is a high-power 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, RF safety requirements, site permissions and lawful drone operation practices. Always connect a suitable antenna or RF load before powering the VTX to prevent RF power-stage damage.
