iFlight BLITZ E55S 55A 2-6S 4-in-1 ESC
Unleash the full power of your FPV drone with the iFlight BLITZ E55S 4-in-1 ESC, a cornerstone of power and reliability. This 30.5×30.5mm electronic speed controller is designed to push the limits of your racing or freestyle drone, supporting up to 6S LiPo input and offering unparalleled current management. It’s the robust power foundation your high-performance build deserves.
Massive Power Handling
The BLITZ E55S is built to handle aggressive, power-hungry setups. It delivers a massive 55A of continuous current per motor with 65A bursts, providing plenty of overhead for the most demanding 5-inch and larger motor/propeller combinations. Fly with confidence knowing your ESC can deliver the power you need, when you need it.
Modern Firmware, Smooth Performance
At its core, the E55S runs on a high-performance BB21 MCU. While it ships with reliable BLHeli_S firmware, it is fully compatible with Bluejay firmware. Flashing to Bluejay unlocks advanced features like bi-directional DShot for RPM filtering, which results in an incredibly smooth and locked-in flight feel with significantly less propwash and vibration.
Key Features:
- Massive 55A Current Rating: A 55A continuous (65A burst) rating provides more than enough power for the most demanding FPV motors on up to 6S.
- Bluejay Firmware Compatible: Unlock modern features like RPM filtering on reliable and affordable 8-bit hardware for a smoother flight.
- 2-6S Versatility: A wide input voltage range makes it a great choice for a huge variety of freestyle and racing builds.
- Durable Construction: Built with high-quality components and a robust PCB layout for maximum reliability.
- Onboard Current Sensor: Provides real-time current draw information to your flight controller for OSD display and flight logging.
