Product overview
The EMAX D-SHOT Bullet Series 20A 2-4S BLHELI_S ESC 3.5g Support Onshot42 Multishot is an electronic speed controller designed for high-level FPV racing, with applications in multirotor builds. It has a 20A ESC rating, a 2-4S input specification and a weight of 3.5g. The supplied option is the default configuration, identified by SKU 0111002008. As a power-control component, it is intended for integration into a build rather than being a complete flight platform or airframe kit.
The controller uses BLHeli-S firmware version 16.5 and hardware PWM to support smoother throttle response and reduced noise. Its control interfaces include digital DSHOT and the analog protocols MULTISHOT, ONESHOT42 and ONESHOT125. Physical construction includes MOSFET components, ceramic capacitors and a 3oz high TG printed circuit board. The board construction is intended to improve heat dissipation and system efficiency, while the named signal protocols define the supported control inputs.
