Foxeer Reaper AIO V4 F745 45A Bluejay BLS 2–6S

The Foxeer Reaper AIO V4 integrates a high-speed STM32F745 flight controller and a 45A ESC into a single lightweight board. Engineered for 2–6S power systems, this all-in-one unit is tailored for 3-inch to 5-inch ultralight freestyle builds, aggressive racers, and high-performance cinewhoops where saving space and reducing weight are critical.

Key features

• Pairs the processing overhead of an F745 MCU with the ultra-low-noise MPU6000 gyro for locked-in tracking and fast loop times.

• The onboard 45A 4-in-1 ESC comes pre-flashed with Bluejay firmware, enabling bidirectional DShot and RPM filtering out of the box.

• Broad 2–6S voltage compatibility easily accommodates versatile motor and battery combinations.

• Utilises the industry-standard whoop/toothpick footprint for direct drop-in integration with modern ultralight frames.
