The Readytosky F405 is a compact all-in-one stack for pilots who want precision, power and reliability. The page describes an F405 flight controller with a high-speed processor, built-in OSD and 16 MB blackbox for in-flight data logging.
The stack also includes a 60A 4-in-1 brushless ESC with BLHeli_S DShot support and an Ultra 5.8GHz 2.5W high-power FPV transmitter. The page lists an input voltage of 3-6S and showed the item in stock.

A flight controller is the brain of a multirotor or fixed-wing aircraft. It reads the gyroscope, and where fitted the accelerometer, barometer and compass, and runs a control loop that compares what the aircraft is doing with what the pilot asks for. It then sends new speed commands to the motors through the ESCs or servos many times each second. A faster processor and a better gyro allow a higher loop rate and a more locked-in feel.
Wiring and firmware decide what the board can do. The number of UARTs limits how many receivers, GPS units, telemetry radios and video systems you can connect, the PWM or motor outputs limit how many motors and servos it can drive, and the input voltage range must suit your battery and power module. Before you buy, check that the firmware you want to run supports the board and that its mounting pattern fits your frame.
Set up carefully. Flash a firmware that is listed as supported, configure the receiver protocol, set the motor order and direction, calibrate the accelerometer and, for larger aircraft, the compass, and always test with the propellers removed first. Keep the board isolated from vibration with soft mounts where the design calls for them, and never power it with a supply that is outside the rated input voltage.
Keep the aircraft safe. Confirm your failsafe settings and arming switch before the first flight, keep a backup of your configuration, and update firmware only when you have a reason to. A flight controller is a safety-critical part, so use the wiring diagram from the maker and avoid guesswork with power connections.
