RC Receivers

The RC receiver (RX) is a small but absolutely crucial component mounted in your FPV drone, airplane, or other remote-controlled model. Its task is to receive control signals sent from your RC radio (via the TX module) and relay them to the flight controller or servos. The reliability of the receiver determines the quality and safety of the radio link.

At Avifly, we focus on offering modern and efficient receivers based on the ExpressLRS (ELRS) standard, which has revolutionized the RC world thanks to its advantages. When choosing an ELRS receiver, pay attention to:

• Operating Frequency:
  • 2.4GHz: The most popular option, offering the highest refresh rates (smoothness) and lowest latency, ideal for freestyle and racing.
  • 868MHz (EU): Provides better range and signal penetration, excellent for Long Range flights.
  Remember, the receiver frequency must match your ELRS transmitter module!
• Antenna Type: Receivers can have a built-in ceramic antenna (shorter range, but no protruding parts – ideal for Whoops) or a connector (IPEX/U.FL) for an external dipole or T-style antenna (better range).
• Telemetry: The function of sending feedback data from the model to the radio (e.g., battery voltage, signal strength RSSI/LQ). Most ELRS receivers support it.
• Diversity: Some receivers have two independent receiver circuits and two antennas, significantly increasing link reliability in challenging conditions (so-called True Diversity).
• Size and Weight: Especially important for micro drones where every gram and millimeter counts.
• Compatibility: Check the ELRS firmware version and the connector type for connection to the flight controller (e.g., via UART port).
• Popular Brands: We offer proven ELRS receivers from manufacturers such as BetaFPV, HappyModel, Radiomaster, and others.

Receivers (RX) is a device inside your drone which receive radio signal from the Transmitter. You should remember that your receiver must be compatible with the transmitter. Most likely your RX works only with transmitter made by the same company.

Selecting the proper ELRS receiver for your model is crucial for ensuring reliable control. Here's what to consider:

• Transmitter Compatibility: Most important! The receiver must operate on the same frequency (2.4GHz or 868MHz) as your ELRS transmitter module in your radio. The ELRS firmware version should also be compatible or easily updatable.
• Model Application:
  • For racing and freestyle (where low latency matters): choose ELRS 2.4GHz.
  • For long-range flights or in areas with obstacles: consider ELRS 868MHz.
  • For micro drones (Whoops, Toothpicks): look for the smallest and lightest receivers, often with a built-in ceramic antenna.
• Need for Telemetry: If you want to receive feedback information on your radio (e.g., drone battery voltage), ensure the receiver supports telemetry (most ELRS do).
• Link Reliability (Diversity): If you fly in challenging conditions or over longer distances, a receiver with "True Diversity" (two antennas) can provide additional safety.
• Antenna Type and Mounting: Consider which antenna type is best for your model and how easily you can mount it. External antennas usually offer better range but require careful placement.

Always check the receiver's specifications and its compatibility with the rest of your equipment before purchasing.

The ExpressLRS system has revolutionized RC control, but choosing the right receiver can still raise questions. Which frequency should you choose: 2.4GHz or 868MHz? Do I need a receiver with diversity? Which antenna is best for my drone? Will this receiver fit my flight controller and radio?
