iFlight BLITZ F745 Flight Controller

The iFlight BLITZ F745 is a 30.5x30.5mm flight controller designed for 5-inch to 7-inch freestyle, racing, and long-range FPV builds. Built around the STM32F745 processor, it offers the computational bandwidth required to run high PID loop frequencies and complex Betaflight filtering, making it a solid foundation for demanding 2-8S setups.

Key features

• STM32F745 MCU paired with the low-noise ICM42688P gyro for precise, responsive flight dynamics.
• Seven full hardware UARTs provide ample connectivity for digital HD video transmitters (including DJI O3, Walksnail, and HDZero), GPS modules, and external receivers.
• Wide 2-8S input voltage tolerance safely accommodates standard 6S rigs alongside high-voltage 8S configurations.
• Standard 30.5x30.5mm mounting pattern drops seamlessly into full-sized freestyle and cinematic frames.
