Performance-Focused Turbo Controller

The Yokomo BL-SP4B packs a turbo throttle feature into a sensored brushless ESC that is both programmable and accessible. It gives precise throttle and brake adjustments that echo the functionality of PRO4/RS4 controllers while remaining budget conscious.

App-Friendly Programming and Updates

Settings can be edited using the optional YBP4 programmer or through a Wi-Fi module and smartphone app. The app enables live setting changes and post-drive graphing for analysis, and future firmware updates are planned to broaden the ESCs capabilities.

Features in a Small Footprint

The BL-SP4B offers boost and turbo behavior along with adjustable power response. It supports forward, auto brake and brake frequency changes plus fine brake tuning. The unit is noted as compatible with a 1-cell LiPo (3.7V), which helps newcomers to brushless systems get started.

For drivers wanting a compact, tweakable sensored ESC, the Yokomo BL-SP4B offers clear programming paths and useful performance modes for track and park use.
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.

Do I need extra parts to use the Wi-Fi setup?

Yes, add the compatible Wi-Fi module to enable smartphone app control. The app then lets you adjust parameters without a wired programmer.

What motor sizes match the BL-SP4B?

This ESC is designed for brushless motors and supports standard small touring motors; turbo mode can extend use up to higher turn motors while keeping smooth sensor operation.

Is the BL-SP4B beginner friendly?

Yes, its compact design and straightforward programming options make it approachable for those moving from brushed to brushless systems, though reading the manual is recommended before first use.
