FrSky RXSR-FC (OMNIBUS F4 Fireworks V2) Flight Controller
Check out all of our FrSky Products!
Dramatically simplify your FPV drone build with the FrSky RXSR-FC OMNIBUS F4 Fireworks V2. This all-in-one flight controller combines the powerful and feature-rich Omnibus F4 platform with a genuine, built-in FrSky RXSR receiver. It’s the ultimate solution for pilots in the FrSky ecosystem seeking a clean, reliable, and high-performance core for their freestyle or racing quad.
Integrated FrSky Receiver for a Clean Build
The standout feature is the integrated FrSky RXSR receiver, which is securely housed in an on-board protection box. This eliminates the need to solder delicate receiver wires, reducing clutter, saving weight, and removing a common point of failure. Simply bind your FrSky radio in D16 mode, and you have a full-range, diversity-capable control link ready to go.
Fireworks V2 Performance
The “Fireworks V2” board is packed with high-end hardware for a premium flight experience. It features a powerful STM32F405 MCU and a sensitive ICM20608 gyro housed in a special dampening box to ensure clean, noise-free flight data. The professional-grade PDB with a 12-layer PCB design and a built-in Hall effect current sensor provides stable, reliable power. For your FPV system, a dedicated 8V BEC with an LC filter delivers noise-free power to your camera and VTX for a crystal-clear video feed.
Key Features:
- Integrated FrSky RXSR Receiver: A full-range, diversity receiver is built-in for a clean, solder-free setup and guaranteed FrSky compatibility.
- Dampened ICM20608 Gyro: A sensitive, high-performance gyro is mechanically isolated in a dampening box to provide exceptionally clean data for smooth flight.
- Filtered 8V VTX Power: Provides clean, noise-free power to your analog VTX and camera for a crystal-clear video signal.
- Professional-Grade PDB: A 12-layer PCB design with a Hall effect current sensor ensures stable power delivery and accurate current monitoring.
- 5 Available UARTS: Plenty of ports for connecting peripherals like GPS, VTX Smart Audio, and more.
- 3-6S LiPo Input: A wide voltage range makes it compatible with a huge variety of FPV drone builds.
IMPORTANT: Protocol Compatibility
The integrated receiver on this flight controller uses the FrSky ACCST D16 protocol. It is ONLY compatible with FrSky transmitters and transmitter modules running in D16 mode. It is NOT compatible with the newer ACCESS protocol.
