Radio components are the backbone of any FPV drone build, enabling reliable communication between your transmitter and drone. From ExpressLRS receivers to RF modules and antennas, every component plays a critical role in range, latency, and signal reliability. At FPVdrones.eu, we stock a wide range of FPV radio components compatible with all major protocols including ExpressLRS, TBS Crossfire, and FrSky. Whether you are building a micro whoop or a long-range FPV drone, you will find the right radio components for your setup.
Frequently asked questions
What is ExpressLRS (ELRS) and why is it popular?
ExpressLRS is an open-source radio protocol known for long range, low latency, and frequent community-driven updates, making it one of the most widely used systems in modern FPV builds.
Do my transmitter and receiver need to use the same protocol?
Yes. Your radio transmitter module and the receiver on your drone must use a matching protocol (such as ExpressLRS, Crossfire, or FrSky) to communicate with each other.
What frequency should I choose for my radio system?
2.4GHz is standard for most builds, while 900MHz and 868MHz options offer better penetration through obstacles for long-range flying at the cost of some latency and antenna size.
Can I upgrade my existing radio system's firmware?
Many ExpressLRS and similar open-source systems support regular firmware updates, which can improve range, reduce latency, and add features — check your specific hardware's compatibility before updating.
