iFlight BLITZ 25mW Race VTX Video Transmitter

The BLITZ RACE 25mW VTX is a race-optimized analog video transmitter designed with an integrated LED control core for streamlined aircraft tracking and simplified field deployment. Engineered specifically for competitive racing environments, this module combines a fixed-power video link with an onboard programmable LED driver that allows independent color and frequency adjustments for attached LED strips. Built with a dual-layer mechanical layout, it natively accommodates both 20×20mm and 30.5×30.5mm mounting patterns. Utilizing a plug-and-play connector interface alongside fully preserved solder pads on the rear panel, the BLITZ RACE offers maximum wiring flexibility for custom racing electronics stacks.

Features

Integrated LED Core Infrastructure: Combines a dedicated 5V 2A LED lighting controller and a video transmitter onto a single hardware platform, streamlining racing frame telemetry setups.

Independent LED Configuration: Allows pilots to manually cycle through addressable LED strip color profiles independently from active video frequencies.

Plug-and-Play Solder Hybrid: Uses standardized micro-plugs for rapid structural swaps while retaining full direct-solder pads on the rear PCB for custom wire routing.

Fixed Power Race Configuration: Locked to a standard 25mW (14dBm) output ceiling to ensure total compliance with competitive racing guidelines and prevent multi-pilot signal blasting in pits.

Dual-Pattern Mounting Chassis: Highly versatile mounting layout configuration natively supports both micro 20×20mm and standard 30.5×30.5mm stack alignments.

Dedicated Hardware Frequency Gate: Features a localized hardware frequency toggle button paired with a dedicated telemetry override loop for automated pitch-side control adjustments.

System Interface Configuration: Physical Tactile Button / Flight Controller OSD Override Capable

Operational Control Logic

Frequency Band Shifting: Short-press the physical CH button to cycle through internal channel profiles.

LED Color Adjustment: Press and hold the CH button for 1 second to cycle through the available independent LED color profiles.

Stealth PIT Mode Control: Press and hold the CH button for 3 seconds to drop into stealth low-power PIT mode. Press and hold for an additional 3 seconds to restore active transmission.

OSD Configuration Override: When a flight controller telemetry link is actively managing the VTX over serial protocols, the local physical CH button is automatically locked out. To restore manual button control, disable the peripheral protocol inside your configurator or physically isolate the VTX RX telemetry wire line.
