The RP4 LED position indicator is designed to be installed in the cockpit and give an indication of the servo output shaft position. The 10 LEDs are the brightest available for superior visibility in sunlight, but can be dimmed for night flight. It can be installed horizontally or vertically.
The RP4 faceplate measures 1.75"(45 mm) X .75”(19 mm) and it is 1.6”(41 mm) in depth. It is now the standard position indicator included in Ray Allen trim systems, or can be purchased separately for special applications such as a cowl or wing flap indicator.
The RP4 includes a RP4-L1 label (featuring Elev1, Elev2, Ail, Rudder, Flaps).
