A friend with an Arrow has a electronic tach. It has a red light that
comes on at 2701 RPM. When he starts the takeoff roll he takes at least
5 seconds to push in full throttle to "prevent the engine overspeed
light from coming on". He also chases the tach constantly during the
takeoff and while flying. "I want 25"/2500, not 2505!" This is why I don't
have an electronic tach....
