iFlight Blitz E55 4-in-1 2–6S ESC

The iFlight BLITZ E55 is a full-sized 4-in-1 ESC engineered for 5-inch freestyle, racing, and 7-inch long-range setups. Rated at 55A continuous and 65A burst per channel, this board handles the sustained amp draw of modern high-kV motors and heavier payloads. Running AM32 firmware, it natively supports active freewheeling and bidirectional DShot for accurate RPM filtering.

Key features

• 55A continuous and 65A burst current handling across all four channels
• Runs 32-bit AM32 firmware for advanced variable PWM frequencies
• Integrated current sensor for accurate battery consumption tracking
• Plug-and-play 8-pin connector allows clean, solderless integration with BLITZ flight controllers
