#RP-0502 - RUDDOG Racing RXB Blinky Stock Brushless Speed Controller

The RUDDOG Racing RXB starts with a new connector and case layout that makes clean builds effortless. Side-mounted solder posts, a front sensor port, and integrated capacitors reduce wire length and clutter for lower resistance and better reliability. On track, the RXB delivers a precise throttle feel and linear braking in a compact 28g package. Its adjustable RPM limit lets clubs and event organizers define a single spec for different motors, turning the RXB into a true control ESC for fair and comparable racing. Reverse polarity protection adds an extra layer of safety, while the adjustable 6.0 to 7.4 V BEC supports both standard and HV servos.

RPM Limit

The RXB lets you set an RPM limit according to the motor’s turn rating. If a class runs 17.5T motors and the RXB is used as a handout or one-make ESC, you can set the RPM limit as mandatory. This is then shown by an additional color LED while the blue LED continues to blink.

• 10.5T: red
• 13.5T: green
• 17.5T: white
• 21.5T: orange

This function can be disabled, so the ESC can be used without an RPM limit. It was designed specifically for one-make series.
