iFlight BLITZ Whoop 5.8GHz 2.5W Analog VTX

The iFlight BLITZ Whoop 5.8GHz 2.5W Analog VTX is engineered for long-range FPV pilots, mountain surfers, and cinematic builders requiring extreme signal penetration from a compact 25.5x25.5 mm whoop-mount footprint. Designed to deliver clean analog video across harsh environments, it integrates an active cooling fan and a CNC-machined aluminium heatsink shell to prevent thermal throttling during sustained high-power transmission.

Key features

• Five switchable output levels (PIT, 25mW, 400mW, 1000mW, and 2500mW) for bench testing, close-proximity flying, and multi-kilometre range
• Active dual-cooling architecture combining a CNC aluminium enclosure and a micro fan to maintain stable RF output
• Whoop-style 25.5x25.5 mm mounting pattern designed to stack cleanly above AIO flight controllers
• Wide 7V to 34V input voltage range supporting 2S to 8S LiPo power systems directly from the battery pad
• Integrated 5V 1A BEC output for powering standard FPV cameras
• Full IRC Tramp protocol compatibility for seamless channel, band, and power level adjustments via Betaflight OSD

Always connect an appropriate 5.8GHz MMCX antenna before powering up the VTX to prevent permanent damage to the RF power amplifier. Ensure your frame provides adequate airflow around the heatsink when operating on the 1000mW and 2500mW power settings.
