Emax F4 Magnum II VTX Transmitter

Order the reliable EMAX F4 Magnum II VTX video transmitter for your drone at an affordable price!

Looking for a compact and smart video transmitter (VTX)? Check out the EMAX F4 Magnum II. This is not just a VTX, but a combo board. It combines the F4 flight controller and video transmitter. Ideal solution for pure FPV builds. Significantly reduces the number of wires. Simplifies installation and reduces overall weight. Great choice for racing drones and freestyle.

Key Benefits

The main advantage is the integrated F4 FC + VTX + OSD board. You get three devices in one case. Saving space and weight is critical to speed. Easy installation speeds up the assembly process. Fewer connections means higher reliability of the entire system. SmartAudio support via UART is absolutely necessary. Change channels and power directly from the remote control. Configure VTX without buttons, via the OSD menu. It is convenient and safe in flight.

The video transmitter operates over a wide range. Supports all popular 5.8 GHz frequencies. 40 channels available (A, B, E, F, Raceband). Transmission power adjustable: 25/100/200/400/600 mW. Choose the optimal one for the distance and rules. Durable aluminum housing - efficient heatsink. It protects electronics and dissipates heat. This guarantees stable operation even at maximum. Overheat protection extends service life.

The flight controller based on STM32F405 is reliable and efficient. Supports current versions of Betaflight. Provides a smooth and responsive flight. The built-in OSD (On-Screen Display) is very useful. Display important telemetry directly to FPV goggles. Battery voltage, timer, RSSI are always before your eyes. Power reverse polarity protection saves the board. A 2A fuse protects against current surges.

Technical features and application

The EMAX F4 Magnum II VTX is designed for miniaturization. Ideal for tiny racing quadcopters. Especially for the popular 3″ and 5″ inch classes. The board's power supply is wide: from 7V to 36V (2-6S LiPo). Connect directly to the power assembly. Built-in BEC 5V/2A powers peripherals. For example, a receiver or an FPV camera. The video input supports both PAL and NTSC standards. Compatible with most FPV cameras on the market.

Setup and management are incredibly convenient. Use Betaflight Configurator for complete setup. Assign modes, PIDs, rates through a familiar interface. Control VTX via OSD or remote control (SmartAudio). Change channel, power, pit mode on the fly. Pit mode (low power mode) is important on the grid. Reduces interference to other pilots before takeoff. The firmware is updated via the USB port (Type-C). Current developer innovations are supported.
