Omnia RPM-ROTOR 57mm is a multifunction engine tachometer with added functions like 4 Hobbs meters, chronometer, automatic flight timer, last flight RPM peak, max RPM peak ever, and an RPM Rotor indicator. The instrument is fully customizable to fit almost any engine. Both indications of engine speed and rotor speed can be represented in absolute value or a percentage value.

All the components of the Omnia family are equipped with a state-of-the-art, highly visible display, a powerful 32-bit microcontroller, and the latest generation of solid-state sensors and components to ensure reliability and accuracy over time.

Omnia RPM-ROTOR 57mm can be interfaced with the Rotax engines I series through the CAN bus

Up to 16 Omnia family instruments can be connected in clusters to form a communication network, making some data exchange operations simpler.

Indications are in absolute values
