Overview
The EMAX Bullet Series is a compact BLHeli_S electronic speed controller (ESC) rated for 35A continuous operation on 3S–6S LiPo setups. It is designed for FPV racing and performance multirotor builds, combining BLHeli-S firmware control with an aluminum heat sink for improved durability and thermal management.
Key Features
- BLHeli-S firmware (16.5) with hardware PWM for smoother throttle response and reduced noise
- Analog signal support: MULTISHOT, ONESHOT42, ONESHOT125
- Aluminum heat sink design to reduce core temperature and help protect against prop strike damage
- High-quality components: Japan Toshiba MOSFET and Murata ceramic capacitors
- 3oz High-TG PCB board to improve heat dissipation and overall efficiency
- High-temperature silicone signal cable for flexible, easier installation

Details

Built for tight FPV stacks, the Bullet Series keeps a compact footprint while supporting 3S–6S power setups.

BLHeli_S control supports MULTISHOT, ONESHOT42, and ONESHOT125 for fast, smooth throttle response.

An aluminum heat sink helps manage core temperature, paired with Toshiba MOSFETs and Murata ceramic capacitors.
