Tunable Sensored Brushless Controller

The Yokomo BL-SP4B is a sensored brushless ESC with a turbo throttle option designed for hobbyists who want detailed throttle and brake control. It brings programmable features familiar to PRO4/RS4 users into a smaller, cost effective unit.

Programming Via Programmer or Smartphone

Configuration is possible with the optional YBP4 programmer or by fitting a Wi-Fi module for smartphone app access. The app enables quick parameter edits and provides post-run graphing for tuning decisions, and further ESC support updates are planned.

Small Form Factor with Performance Modes

In a compact case the BL-SP4B still delivers boost and turbo modes along with adjustable power character. It includes forward, auto brake and brake frequency adjustment functions and allows fine brake setting. It is listed as compatible with a 1-cell LiPo battery (3.7V), which helps new brushless users get started.

Specifications

  • Compatible Motor: Brushless 8.5T (13.5T with turbo)
  • Input Voltage: NiCd/NiMH: 4–6 Cell, LiPo/LiFe: 2 cells
  • BEC Voltage: 6.0V/3.0A
  • Case Size: 29.1x29.0x18.5mm (excluding protrusions)

Overall, the Yokomo BL-SP4B is a solid pick for modellers seeking a compact, programmable sensored ESC with turbo capability and accessible setup options.
