iFlight BLITZ Whoop 1.2G 1.6W VTX Video Transmitter

The iFlight BLITZ Whoop 1.2G 1.6W VTX is a high-power video transmitter engineered for specialized long-range FPV operations within the alternative 1.2GHz frequency spectrum. Delivering 5 adjustable power stages up to a high-penetration 1600mW output ceiling, it guarantees exceptional signal propagation, dense obstacle penetration, and robust link stability across expansive operating boundaries. This VTX features a built-in power output self-test mechanism and an optimized RF architecture that enables ultra-fast frequency locking, preventing startup signal drift and protecting nearby pilots from video blinding. Outfitted with a wide 7V to 34V voltage tolerance, its unique micro form factor features a 25.5×25.5mm mounting layout, natively supporting Betaflight VTX table configurations via the standardized IRC Tramp telemetry protocol for effortless remote parameter tuning.

Features

Specialized 1.2GHz Spectrum: Operates within the lower 1.2GHz band, which inherently offers significantly better object penetration and lower atmospheric attenuation than standard 5.8GHz systems.

High-Output Power Scaling: Outfitted with 5 adjustable power steps capable of stepping from stealth PIT mode up to a powerful 1600mW (1.6W) maximum output, making it ideal for specialized deep-range aircraft tracking.

RF Power Output Self-Check: Integrated hardware calibration circuitry automatically runs a power output self-test to ensure consistent, clean transmission levels across all operational states.

Rapid Frequency Locking: Advanced RF synchronization logic locks onto the selected frequency instantly upon boot, suppressing startup signal drift and protecting nearby pilots from video blinding.

IRC Tramp Telemetry Interface: Seamlessly integrates with standard IRC Tramp protocol fields, allowing pilots to modify video channels, bands, and power steps directly through the Betaflight OSD.

Expansive Frequency Spectrum: Operates across a comprehensive 40-channel matrix spread evenly over 5 frequency bands, fully incorporating a highly stable Raceband corridor to minimize inter-pilot signal washing.

Micro Whoop Mounting Core: Highly unique structural design fits a standard micro-sized 25.5×25.5mm mounting pattern, allowing ultra-high-power 1.2GHz deployment inside lightweight whoops and toothpick frames.

Notes

Before use install the antenna. Running a high-power 1.2GHz VTX without a matching antenna will cause instant, catastrophic damage to the RF amplifier stage.

Fly with constant airflow and in a well-ventilated environment to prevent overheating. Operating transmission profiles on the 1.2GHz band requires specialized operator licensing and regulatory approval in most jurisdictions.

Betaflight Integration: To ensure proper telemetry operation and exact power level matching, make sure to flash the dedicated 1.2G Betaflight VTX table into your flight controller configurator.
