Overview
The iFlight BLITZ H7 Pro Combo is a high-performance flight controller and ESC solution designed for demanding long-range and heavy-lift FPV drones. With support for 4S to 12S Lipo, an STM32H743 MCU, and up to 80A continuous current, it delivers professional-grade performance and durability. Users can choose from two configuration options:
-
Combo 1: H7 Pro FC + 1× E80 ESC
-
Combo 2: H7 Pro FC + 2× E80 ESCs (for redundant/power-split builds)
The ESC also offers an optional CNC aluminum heat sink cover for advanced thermal protection and EMI shielding, especially for high-amperage builds.
