Yokomo ESC BL-PRO4 Turbo (>3.5T) with wire

Yokomo have updated their line of high-performance brushless speed controllers and now introduce the BL4 series. The range includes the BL-Pro4, BL-RS4 and BL-SP4 with the BL-Pro4 being a top-of-the-foodchain ESC with an all-aluminium case, 1-cell LiPo booster, a new cooling fan and an aluminium cooling fan guard. A new firmware allows for better control over the boost, turbo delay and slope functions as well as the brake frequency. On top of this the controller sports all-black wiring for that cool factory look.

The BL-RS4 pretty much builds on the Pro4, it comes without cooling fan and sports black receiver and on/off switch wires like the Pro4. Last but not least comes the sport-level BL-SP4, a compact unit with newly-added turbo functions for stock racing and a variety of features aimed towards entry-level racers.
