The IRS 100A 8S 4-in-1 ESC is a high-current electronic speed controller developed for demanding FPV racing, freestyle, and heavy-load multirotor applications. Designed in a compact 4-in-1 format, it controls four brushless motors from a single board while helping reduce wiring complexity and overall stack weight. Its wide 3S–8S LiPo input range makes it suitable for powerful FPV builds that require strong acceleration, fast throttle response, and dependable current delivery. Built around an EFM8BB21/BB51 MCU, high-performance MOSFETs, and support for DSHOT300 and DSHOT600, the ESC is optimized for responsive motor control and stable flight performance. It provides 100A continuous current per channel with up to 110A peak current for 10 seconds, giving additional headroom for aggressive maneuvers and high-load propulsion setups. The standard 30.5 × 30.5 mm mounting pattern and 14-pin plug-and-play flight-controller interface make installation straightforward for compatible FPV stacks.
