The EMAX F4 Magnum II video transmitter (VTX) is a high-performance video transmitter designed for FPV drone racing and aerial photography. With an adjustable power output from 25mW to 200mW, it offers strong range and signal strength whether you are chasing gates or capturing aerial footage.
Its compact size and lightweight construction make it an easy fit in a wide range of drone frames and FPV setups, giving a sleek, streamlined overall build.
The listing describes the transmitter as delivering a clear, stable video feed with minimal interference, which is what a racing pilot needs when the aircraft is moving fast and close to obstacles.
Adjustable 25mW to 200mW output: turn the power down for close-in racing, up for range.
37 channels: flexibility to pick a clear frequency.
Compact size: integrates into various drone frames and FPV setups.
Lightweight composite build: keeps the extra weight on the aircraft small.
Stable video signal: designed for a clear feed with minimal interference.
A video transmitter's output power decides how strong your video signal is at range. Racing pilots often fly at low power, so they interfere less with each other, and long-range pilots turn the power up. An adjustable VTX lets one part cover both cases.
Higher power also produces more heat and uses more current, so being able to select a level that suits the flight is useful for both performance and battery life.
