iFlight Blitz E55R 4-in-1 ESC

The iFlight BLITZ E55R is a heavy-duty 4-in-1 ESC engineered for 5-inch freestyle, aggressive racing, and 7-inch long-range builds. Designed to reliably drive high-kV motors and steep-pitch props, it delivers 55A of continuous current and absorbs transient spikes up to 65A. The ESC integrates a custom CNC-machined aluminium heatsink casing, which shields the sensitive surface-mount components from prop strikes and rapidly dissipates heat during sustained throttle pulls.

Key features

• Sustains 55A continuous and 65A burst current to support power-hungry setups.
• Enclosed in a CNC aluminium heatsink shell for superior thermal dissipation and physical protection.
• Runs high-frequency BLHeli_32 firmware for ultra-smooth motor tracking and efficiency.
• Fully supports bidirectional DShot and RPM filtering out of the box.
• Integrated onboard current sensor for precise battery consumption telemetry.

Specifications

• Input voltage: 2-6S LiPo
• Continuous current: 55A
• Burst current: 65A
• Firmware: BLHeli_32 (Target: IFLIGHT_BLITZ_G2)
• Current sensor scale: 200
