iFlight BLITZ F7 V1.2 + E55 4-in-1 55A ESC Stack

The iFlight BLITZ F7 Stack is a professional-grade, full-sized propulsion and control system designed for 5-inch to 7-inch freestyle, racing, and long-range sUAS platforms. This V1.2 iteration features a critical hardware upgrade to the ICM42688 gyro, offering superior vibration resistance and cleaner data for high-fidelity flight tuning compared to previous MPU or BMI-based versions. The flight controller is built around the high-speed STM32F722 MCU, ensuring it can effortlessly handle the latest Betaflight and INAV features while maintaining ultra-low loop times.

The paired BLITZ E55 4-in-1 ESC is an industrial-strength power hub capable of delivering a continuous 55A per channel. Utilizing high-quality MOSFETs and a dedicated G071 MCU, the ESC provides the rapid response times and high-torque authority needed for tactical maneuvers and heavy-lift cinematic flights. A standout feature of this stack is its plug-and-play DJI HD VTX connector, which allows for a solder-free connection to DJI O3 or Air Units, significantly simplifying the assembly of digital reconnaissance and photography drones. With an integrated LC filter and dual high-current BECs (5V and 9V), the BLITZ F7 Stack provides the clean, reliable power management required for mission-critical reliability in the field.
