Sub250 Redfox A3 F722 45A AIO Flight Controller

Sub250 Redfox A3 F722 45A AIO Flight Controller

Product description

The Sub250 Redfox A3 45A is a powerful all-in-one flight controller board that combines flight control (FC) and ESCs in a single compact unit.
This board is the perfect choice for 3-4 inch freestyle drones, cinewhoops and even lightweight 5-inch setups powered by 2-6S LiPo batteries.

Thanks to the external USB-C connector on a flexible cable, the Redfox A3 is particularly convenient to install - a real advantage when building cinewhoops, where access to connections is often limited.

At its heart is an STM32F722 processor in combination with an ICM42688-P gyro sensor, which ensures precise control, high flight stability and fast response times.
The flight controller also has an integrated OSD for analog video signals, a barometer for altitude measurement and a 5V/2.5A BEC to safely supply additional components such as receivers, LEDs or GPS modules.

The integrated 45A ESCs run with BLHeli_32 firmware and offer sufficient power even for powerful motors. A built-in current sensor supplies precise telemetry data to the flight controller.

The Redfox A3 45A thus combines maximum performance, reliability and ease of installation - ideal for pilots who prefer a clean and easy setup.
