R-1 Tachometer

R-1 Tachometer

The R-1 displays an accurate RPM measurement in digital and analog format.

Quick, Yet Stable Readings

Proprietary algorithms ensure that the RPM reading is rock solid when the engine settings are stable, but with the slightest touch of the controls, the R-1 Tachometer will respond with lightning-quick rapidity. There is simply not a finer tachometer available, hands down. The R-1 is STC’d as a Primary Replacement Instrument, so you can legally replace your existing tachometer.


The R-1 is a Primary Replacement, FAA TSO’d and STC’d instrument.
