iFlight BLITZ E55R 4-IN-1 ESC Built like a little tank but sized for tight builds, the BLITZ E55R 4-IN-1 ESC from iFlight delivers big-quad power in a compact 20×20 mini stack format. Designed for aggressive freestyle and race setups, it combines BLHeli_32 smoothness, high current handling, and improved thermal design so you can push hard without cooking your electronics. The upgraded “R” layout uses larger MOSFETs and thicker copper traces for better heat dissipation and durability, giving cleaner throttle response and more confidence during punch-outs, propwash recoveries, and heavy 6S abuse. Built-in current sensing and ESC telemetry feed real data back to your flight controller, helping with tuning, efficiency checks, and battery management. With 2–6S support, fast DShot protocols, and a simple plug-and-play harness, installs stay clean and reliable — perfect for modern 5″ rippers, lightweight racers, or compact freestyle builds that still demand serious amps.
