SpeedyBee F405 V5 OX32 55A 30x30 Model Aircraft FC & ESC Stack

The SpeedyBee F405 V5 OX32 55A Stack represents the next generation of flight electronics, meticulously engineered for the RC hobby market, FPV drone racers, and professional sUAS manufacturers. This high-performance 30x30 stack combines a feature-rich F405 V5 Flight Controller with the robust OX32 55A 4-in-1 ESC, offering unparalleled reliability for everything from high-intensity freestyle builds to educational STEM programs and government/military tactical drones.

At the heart of the V5 stack is the Wireless Tuning 2.0 system. Powered by an onboard ESP32 Bluetooth chip, it allows pilots to flash firmware, tune PIDs, and configure settings wirelessly via the SpeedyBee App on a smartphone. This eliminates the need for field laptops, making it a favorite for sUAS contractors and field operators. The FC is equipped with the high-precision ICM42688P Gyroscope, featuring an independent high-PSRR LDO to isolate power noise and ensure ultra-smooth flight telemetry. With its built-in 16MB Blackbox flash memory, you can record and analyze flight logs without the reliability issues of SD cards.

The OX32 55A ESC provides a genuine 55A continuous output (220A total) and can handle bursts up to 70A, making it ideal for high-powered 6S motor setups. It features a massive aluminum alloy heatsink for superior thermal management and a built-in TVS protective diode to absorb voltage spikes during aggressive flying or crashes. Designed for versatility, this stack supports Betaflight, INAV, and Ardupilot, providing a flexible platform for high school and college engineering projects as well as commercial drone development.
