Redfox A1 F4 5A 4in1 1S AIO FC with VTX 200mW for Analog Drones

Redfox A1 F4 5A 1S AIO Flight Controller w/ 200mW VTX | Ultra-Light Micro Drone Board

Simplify your next 1S micro drone build with the highly integrated Redfox A1 All-In-One (AIO) Flight Controller. This compact board combines a powerful F4 flight controller, a capable 4-in-1 5A ESC, and an onboard 200mW analog video transmitter (VTX), making it the perfect brain for your Whoop, Toothpick, or custom lightweight FPV drone.

Designed specifically for 1S LiPo operation, the Redfox A1 dramatically reduces wiring complexity, saves precious weight, and streamlines the building process. Get smooth and responsive flight performance thanks to the F4 processor running your favorite firmware (like Betaflight or Emuflight – check compatibility). The 5A ESCs provide ample power for typical 1S motors (e.g., 07xx, 08xx, 1002 sizes), while the integrated 200mW VTX delivers clear analog FPV video transmission with decent range for park flying and indoor adventures.

If you’re searching for a reliable, feature-packed, and easy-to-install AIO FC for your 1S FPV build, the Redfox A1 offers an excellent balance of performance, integration, and value. Build smaller, fly lighter!
