Video transmitter iFlight BLITZ 5.8GHz 1.6W VTX

The BLITZ 5.8GHz 1.6W VTX is a high-power analog video transmitter engineered for long-range and freestyle FPV platforms. Delivering 5 adjustable power stages up to a high-penetration 1600mW output ceiling, it guarantees exceptional signal propagation 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 signal interference when powering up in the pits near other pilots. Outfitted with a wide 7V to 34V voltage tolerance, it natively supports Betaflight VTX table configurations via the standardized IRC Tramp telemetry protocol for effortless remote parameter tuning.

Features

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 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.

Broad Voltage Compatibility Matrix: Supports a wide input voltage corridor from 7V to 34V DC, enabling hassle-free direct power integration straight from 2S to 8S LiPo battery mainlines.

Notes

Factory Default Power Step: For safety and regulatory compliance, the VTX is pre-configured out of the box to a standard 25mW output ceiling. High-power settings must be manually unlocked via the firmware configuration.

Before use install the antenna. Running a high-power VTX without an 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 above 25mW may require specific operator licensing or local regulatory approval depending on your region.
