Series 1520/1580/1585 - Optical RPM Probe V1
This product is an optical rotation speed sensor for the motor on your RCbenchmark Series 1520/1580/1585. Directly connect this probe to the “Servo1” plug, and you are good to go. It comes with reflective tape. The instructions to install the probe are in the RCbenchmark software.
Note that we have a newer version that comes with mounting hardware (see the accessories section on the right).
Use this optical probe if you have issues with the electrical probe included in your Series 1520/1580/1585. The optical probe is recommended for low Kv motors (<700 Kv), for very high-speed motors (>150 000 eRPM), or if you want to use brushed motors.
