The R-1-N1 displays an accurate N1 RPM measurement in digital and analog format. 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-N1 Tachometer will respond with lightening quick rapidity. There is simply not a finer tachometer available, hands down.
The R-1-N1 displays N1 RPM in a 210 Degree graphical LED arc for immediate reference. Red and Yellow LED’s highlight cautionary and restricted operating ranges.
The R-1-N1 keeps track of Tach Time on your engine, to .1 hours.
Flight Time is recorded from takeoff to landing.
For every flight, Peak RPM is stored. Simply press the “Pk” button to see the previous flight’s Peak RPM.
