About the BL-RPX4 Race ESC
Precision Throttle Response
The Yokomo BL-RPX4 Race ESC is powered by an advanced 32-bit Super Speed CPU, delivering ultra-fast processing for flawless throttle input and instant motor response. With smooth, controllable power at low RPMs and explosive acceleration at high speeds, racers can maintain maximum efficiency and precision through corners and straights. This ensures consistent lap times and complete confidence under competitive conditions.
Race-Optimized Design
Developed in collaboration with Team Yokomo, the RPX4 comes preloaded with race-tuned programs for on-road and touring car competition. Adjustable Boost and Turbo timing unlock maximum acceleration, while refined power mapping ensures smooth delivery on high-grip surfaces. Available in anodized black, blue, purple, and red, the RPX4 delivers both peak performance and striking style for serious racers.
Advanced Cooling System
Engineered with a full aluminum housing and integrated cooling fan, the RPX4 maintains stable operation under extreme race conditions. High-grade FETs, advanced heat dissipation, and multiple safety protections safeguard against voltage drops, signal loss, and overheating. With adjustable BEC output (5–7.4V) and variable frequency control, racers can fine-tune efficiency and reliability to match any track or motor setup.
