Overview
This tiny tachometer mounts inconspicuously on your model and lets you safely monitor RPM while you stand behind the spinning  propeller. Connected via the included y-harness, it works by precisely counting ignition pulses. Handy against RF interference too because it'll indicate 0 RPM (or varying RPM) as a warning.
