The flight controller is the brain of your FPV drone, processing sensor data and translating your stick inputs into precise motor commands. A good flight controller runs Betaflight or other open-source firmware and supports features like GPS rescue, OSD, and blackbox logging. Browse our selection of FPV flight controllers at FPVdrones.eu, including F4, F7, and H7 processors, suitable for micro builds, 5-inch quads, and long-range drones.
Frequently asked questions
What's the difference between F4, F7, and H7 processors?
These denote processing power and clock speed. F4 is sufficient for most freestyle and racing flights, F7 offers more processing headroom for features like GPS rescue and advanced filtering, and H7 is the most powerful, suited to the most demanding setups.
Do the flight controller and ESC need to be from the same brand?
No, but compatibility matters: check that the mounting pattern (stack size, e.g. 20x20mm, 30.5x30.5mm) and firmware (BLHeli, Betaflight) are compatible.
What is stack size and why does it matter?
Stack size (e.g. 20x20, 25.5x25.5, 30.5x30.5mm) determines which flight controllers and ESCs will physically fit your frame. Always check your frame manufacturer's specification before buying.
Do all flight controllers support Betaflight?
Most modern FPV flight controllers support Betaflight, though some — especially long-range and autonomous setups — use INAV. Check the product description to confirm compatibility with your use case.
