iFlight BLITZ Mini E55S 4-in-1 ESC V1.1

The iFlight BLITZ Mini E55S V1.1 is a compact 20x20mm 4-in-1 electronic speed controller engineered to deliver 55A continuous current per channel for 2-6S FPV racing and freestyle builds. Designed for tight frame clearances without sacrificing output capacity, it handles aggressive throttle bursts up to 60A on high-performance 5-inch and heavy-duty sub-250g setups.

Key features

• Delivers 55A continuous and 60A burst current per corner across a 2-6S LiPo voltage range
• Compact 20x20mm mounting pattern fits modern mini stacks and space-constrained FPV frames
• Runs BLHeli_S firmware with full support for DShot150, DShot300, and DShot600 protocols
• Integrated onboard current sensor (scale: 200) for accurate mAh consumption tracking via OSD
• Heavy-duty copper PCB layout improves heat dissipation during sustained high-amp draw
