Yokomo BL-PRO4BB High-Performance Brushless Controller

The Yokomo BL-PRO4BB speed controller upgrades the BL series with finer control and expanded tuning options for RC racers. It includes adjustable boost mapped by motor rpm and throttle, turbo lay and slope settings, plus selectable brake frequency to match driving preferences.

Robust Cooling and Long-Lasting Build

Housed in a full aluminum case for improved heat dissipation, the BL-PRO4BB is built to handle demanding track conditions. A larger cooling fan paired with an aluminum fan guard improves airflow and protects internal components during sustained runs.

Straightforward Fitment and Connectivity

Battery and motor leads arrive pre-soldered for quick installation so you can get back on the track faster. Program adjustments are available via the optional YBP4 programmer, and the BL-WM Wi-fi module lets you change settings and view live data from a smartphone app when installed.

Keep the fan and vents clear, use proper gear ratios to reduce motor load, and consider additional cooling breaks between runs to maintain consistent performance.
