Warns by light and horn of any danger of
an approaching stall regardless of the flight maneuver. Never signals unless
a stall is imminent. Consists of an instrument panel unit (fits standard
2-1/4" hole) containing a warning horn and signal light, and a small vane
wing unit which operates a relay. Operation of the instrument does not depend
upon air speed but rather on the air flow conditions of the wing. Complete
with installation kit & instructions. Installation time: 26 hrs.
