Yokomo BL-SP4B Brushless Turbo ESC - Programmable  [BL-SP4B]

Compact Sensored ESC with Turbo Mode

The Yokomo BL-SP4B brings turbo throttle control to a sensored brushless ESC designed for tunable performance. It provides detailed throttle and brake shaping comparable to higher-end PRO4/RS4 type controllers while remaining wallet friendly.

Flexible Programming Choices

Adjustments are possible via the optional YBP4 programmer or by fitting a Wi-Fi module to use the smartphone app. The app supports on-screen parameter changes and displays post-run data in graphs, with possible ESC updates expected later.

Tunable Output, Small Size

Although small, the BL-SP4B includes boost and turbo functions plus an adjustable power feeling. It supports forward, auto brake and brake frequency adjustments and allows fine brake tuning. It is reported to be compatible with a 1-cell LiPo battery (3.7V), which can suit entry-level brushless conversions.

The Yokomo BL-SP4B is a compact choice for modelers seeking brushless performance with plenty of tuning options in a small package.
