Product overview

The iFlight BLITZ Mini F7 Stack (E55S Mini 4-IN-1ESC) combines a BLITZ Mini F7 V1.2 flight controller with a BLITZ Mini E55S 4-IN-1 ESC for recreational use. The flight controller is mainly used with Betaflight, and the product does not support autonomous flight. Its STM32 F722 processor works alongside an ICM42688 gyro, DPS310 barometer and AT7456 OSD chip, with 8MB of Blackbox flash. Improved circuit design and components reduce electrical noise, while indicator LEDs support visual debugging.

The flight controller measures 30.5x27 mm, weighs 5g and uses a 20x20 mm / φ4 mount pattern. Its DJI HD VTX connector allows plug-and-play connection without soldering, with Smartaudio and IRC Tramp support also provided. The 11.3g ESC accepts 2-6S LiPo input and carries constant and burst current ratings of 55 Amps and 65 Amps. It includes a current sensor and has no BEC. The package supplies both boards, silicon grommets and a wire harness for the F7 flight controller.
