iFlight BLITZ Whoop 5.8GHz 2.5W VTX Video Transmitter

The BLITZ Whoop 5.8GHz 2.5W VTX from iFlight — is a compact and high-performance video transmitter for FPV drones (category: Drones & Quadcopters > Transmitters), combining powerful signal transmission, reliability, and advanced customization options. The device operates in the 5.8 GHz band and supports adjustable output power from PIT/25 mW to 2500 mW (34 dBm), making it suitable for both racing and freestyle drones.

The transmitter features 40 channels, including Raceband, and is equipped with a built-in high-quality microphone with automatic gain control (AGC) for audio transmission. For continuous long-term operation, an active cooling system with an integrated fan is installed, and a durable CNC-machined aluminum alloy casing ensures efficient heat dissipation and longevity. The casing color is black.

The power supply accepts a wide voltage range from 7 to 34 V DC (supporting 6S–8S LiPo), and also provides stable 5V (500 mA) power for peripheral devices. The antenna connector is MMCX, and the mounting standard is 25.5×25.5 mm (Ø1.6), allowing for easy integration of the module into many frames and platforms. The transmitter also supports VTX telemetry via the IRC Tramp protocol, has an LED status indicator, and a functional control button for quick mode changes.

Key Features and Benefits

• High output power up to 2500 mW (34 dBm) with PIT/25 mW/400 mW/1000 mW/2500 mW modes for various flight conditions.
• Wide input range of 7–34 V DC, compatible with 6S–8S batteries.
• Built-in microphone with automatic gain control (AGC) for high-quality audio transmission.
• Active cooling with an integrated fan for stable operation under load.
• Convenient antenna connection via MMCX and standardized 25.5×25.5 mm (Ø1.6) mounting.

Setup and Compatibility: Frequency adjustment is possible both automatically and manually; OSD is supported via Betaflight/Cleanflight for displaying video signal parameters in the flight OSD. The module complies with international CE, FCC, and RoHS standards, confirming its quality and operational safety.

Operating Recommendations: Before connecting, check the antenna connection, power supply voltage, and contact reliability; ensure sufficient ventilation space around the VTX to avoid overheating protection activation. Adhering to these simple rules will extend the module's service life and maintain stable image and sound transmission.
