210 Degree Arc
The R-1 displays 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 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.
The drop in RPM when switching from "Both" mags to "Left" or "Right" on your ignition switch is
displayed on the large, crisp LCD of the R-1. For instance, if the drop is 110, the R-1 will display "-110."
Mag Failure Alert
If a mag fails during your flight, the R-1 will alert you by intermittently cycling through the LED's several times as you make
your approach to land. Several pilots have mentioned to our support staff that this "cycling" has caught a failed mag
while in flight.
