This probe is compatible with the Series 1520 and the Series 1580, though you will need to provide your own bracket to install it on the Series 1580.

Depending on the width of your motor, you can adjust the position of the optical RPM probe with a combination of spacers.

The Series 1520 comes with an electrical RPM probe that may or may not be compatible with your motor/ESC/voltage combination. This probe is an alternative for situations where the electric probe does not meet your specific needs.
