iFlight BLITZ Mini F745 Stack (F7 FC + Mini E55 4-in-1 ESC)

The iFlight BLITZ Mini F745 Stack pairs a high-performance BGA-STM32F745 flight controller with a robust 55A 4-in-1 ESC in a compact footprint. Engineered for demanding 5-inch freestyle quads, aggressive racers, and lightweight cinelifters, this stack delivers heavy-duty processing headroom and reliable current handling for modern 6S powertrains.

Key features

• High-speed BGA-STM32F745 processor ensures rapid loop times and provides abundant hardware UARTs for GPS, telemetry, and extra peripherals.

• Dedicated dual BECs supply clean, interference-free power to HD video systems and RC receivers.

• Generous 55A continuous (65A burst) ESC capacity handles high-kV motors and aggressive throttle punch-outs without bottlenecking.

• Pre-wired plug-and-play sockets for DJI O3 and other digital VTX units streamline the build process and minimise micro-soldering.
