Receivers for FPV Drones and Quadcopters

A drone receiver is a module that receives a signal from the transmitter and relays it to the drone's system. For control, the receiver gets commands from the remote and sends them to the flight controller. If it's an FPV receiver, it receives the video signal from the drone so the operator can see the image in goggles, on a monitor, or via a ground station.

The main types are FPV receivers for video and RC receivers for control. An FPV receiver works with the image: it receives a video signal from the transmitter on the drone. An RC receiver is responsible for flight commands — throttle, turns, modes, arming, and other actions from the remote control. These are different tasks, so it's important not to confuse the video channel and the control channel when choosing.

The weight of receivers can range from a few grams for compact RC modules to noticeably heavier FPV solutions for goggles or ground stations. For a lightweight drone, every extra gram affects balance, flight time, and frame load. On larger platforms, there is more weight allowance, but it is still best to plan the placement of the receiver, antennas, and wires from the start.

Modern receivers operate in various bands, depending on whether they receive video or control signals. For radio control, 433 MHz, 868 MHz, 915 MHz, and 2.4 GHz are often used. For FPV video, 5.8 GHz, 1.2/1.3 GHz, 3.3 GHz, and other bands are common. The frequency must match the transmitter and antenna; otherwise, the system will simply not provide a stable connection.

Diversity is a technology where a receiver operates with two antennas or two receiving channels and selects the stronger signal. This helps reduce communication dropouts when the drone changes position, flies behind an obstacle, or enters an area with signal reflections. For FPV, this is especially useful: the picture remains more stable, and control is less dependent on a single unfavorable antenna position.

Receivers are used for FPV flights, racing, aerial photography, training assemblies, and long-range flights where connection stability is crucial. For racing, low latency, light weight, and quick response are more important. For aerial photography, a stable signal and compatibility with the camera, goggles, or monitor are essential. For long-range flights, factors like frequency, antennas, protocol, and signal reception margin are considered.

Drone receivers in Ukraine are priced from UAH 300. The cost then depends on the receiver type, frequency, protocol, number of antennas, Diversity support, range, connection format, and package contents. A simple RC receiver for control and an FPV receiver for video can differ significantly in price, as these are different modules for different tasks.

Drone receivers can be ordered from Flash Army — for control, FPV video, or a specific build for a required frequency range. Here, you can conveniently check compatibility with the transmitter, antenna, flight controller, and remote control right away, to avoid assembling the system at random. Orders are quickly dispatched across Ukraine, so you can receive the necessary module without a long wait.
