The new RP4 LED position indicator is designed to be installed in the cockpit and give an indication of the trim 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 an RP4-L1 label (featuring Elev1, Elev2, Ail, Rudder, Flaps).
An RP4-L2 label (featuring Cowl Flaps, < >, on/off) is also available on request.
** This indicator supercedes the RP3 indicator.
The RP4 indicator uses ten LED lights to show the position of a actuator output shaft (or position sensor arm). There are also two amber colored LED's, one on each end of the indicator scale, to act as a reference for the green indicator light, especially in dark conditions.
The RP4 is panel mounted using a faceplate and two countersunk, 2-56 x 7/16” screws. Use care when installing these screws, the mounting holes are tight (two spare finishing screws are included). Note that the distance between the screw holes is identical to the older Ray Allen RP3 LED indicator. Although the faceplate dimensions are identical between the RP3 and RP4 indicators, the panel cutout size is slightly different between the RP3
and RP4. If you are replacing and older unit with a new RP4, you will only need to increase the size of your panel hole (see Panel Cut Out). The RP4 faceplate will cover the older RP3 panel hole.
