iFlight BLITZ Whoop 5.8GHz 2.5W Analog VTX

The iFlight BLITZ Whoop 5.8GHz 2.5W VTX is a high-power analog video transmitter in a 25.5x25.5mm whoop-mount footprint, built for long-range and mountain-surfing pilots who need to punch through at up to 2.5W.

Key features

• Five switchable power levels — PIT, 25mW, 400mW, 1000mW and 2500mW — for bench testing through to multi-kilometre range.
• CNC aluminium housing with an integrated cooling fan keeps output stable at high power.
• Whoop-style 25.5x25.5mm mounting stacks cleanly above AIO flight controllers.
• Wide 7–34V input (2S–8S) runs straight off the battery pad.
• Full IRC Tramp support for channel, band and power adjustment from the Betaflight OSD.
• 40 channels including Raceband, with a self-check on output power at startup.
• Built-in microphone for onboard audio.

Specifications

• Output power: PIT, 25mW, 400mW, 1000mW, 2500mW
• Channels: 40 (including Raceband)
• Input voltage: 7–34V (2–8S LiPo)

Fit a 5.8GHz MMCX antenna before powering the module on — running it without one can damage the RF amplifier — and make sure your frame gives the heatsink airflow at the 1000mW and 2500mW settings.
