Compact Turbo ESC Built for Hobby Racers

RC hobbyists looking for a balance of performance and value will find the Yokomo BL-SP4B a practical choice. This sensored brushless speed controller includes a turbo throttle function to raise top speed and offers programmable throttle and brake settings similar to PRO4/RS4 units.

Wireless Setup and Logging Options

Program changes can be made with the optional YBP4 programmer or by adding a Wi-Fi module for smartphone control. The app lets you tweak settings on-screen and review post-run graphs. Firmware updates to expand ESC compatibility are expected in future releases.

Small Package, Tweakable Output

Despite a compact case, the BL-SP4B delivers boost and turbo modes plus an adjustable power feel. It supports forward, auto brake and brake frequency adjustments with precise brake tuning. The controller is also reported to be compatible with a 1-cell LiPo battery (3.7V), making it approachable for those new to brushless setups.

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)

The Yokomo BL-SP4B suits hobbyists upgrading to brushless power who want compact hardware and extensive tuning options for a variety of RC applications.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Which programmer works with the BL-SP4B?

Use the BL-YBP4 programmer for wired configuration. The BL-SP4B is designed for the new programmer and will not work with older Yokomo programmer models.

Can I use the BL-SP4B for drifting setups?

Yes, it can be used for drift, and many builders pair it with motors 13.5T or smaller for predictable slide control while using the turbo mode selectively.

How should I mount and cool the ESC?

Mount it where airflow can reach the case and avoid direct contact with chassis parts that trap heat. Use double-sided foam tape or a low-profile mount and keep connectors tidy to aid cooling.
