MicoAir 50A Bluejay 4-in-1 ESC

The MicoAir 50A Bluejay 4-in-1 ESC ships pre-flashed with Bluejay firmware, giving 5-inch freestyle and racing builds native bidirectional DShot and RPM filtering without a separate firmware flash.

Key features

• 50A continuous current per motor output, enough headroom for aggressive 5-inch freestyle and race throttle punches.
• Pre-installed Bluejay firmware enables bidirectional DShot and RPM filtering straight out of the box.
• Standard 30.5x30.5mm mounting footprint fits the majority of mid-size flight controller stacks.
• Wide 2-6S LiPo input range covers everything from lightweight 4-inch quads to hard-hitting 6S freestyle rigs.

Match this ESC with motors and propellers that stay within its 50A continuous rating, and bench-test the combination before committing to full throttle on a new build. Bluejay's DShot300/600 support keeps motor signalling clean at high loop rates, which helps on tightly tuned freestyle setups.
