The RAY ALLEN (RAC) RP4 LED position indicator is designed to be installed in the cockpit providing an indication of the servo output shaft position. This indicator supercedes and it is a direct replacement for previous RAC RP3. 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 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 RAC RP4 position indicator is panel mounted using a faceplate and two countersunk, 2-56 x 7/16" screws (two spare finishing screws are included). 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. The RP4 faceplate will cover the older RP3 panel hole.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). A RP4-L2 label (featuring Cowl Flaps, < >, on/off) is also available and is sold separately. 

NOTE: Labels can only be ordered together with . In ordering these high quality labels please be advised that rocker switches and needle indicators require a large label, LED indicators use a small label. Can be only included in orders of respective RP4 position indicator(s) (not separately).

Accelerometers (aka G-Meters) are used extensively in a wide range of applications including Aviation, Marine, Automotive, Military, and others. They are also used  in inertial navigation and guidance systems in airplane and ship autopilots.They help in a better understanding of static, such as gravity, or dynamic forces due to motion or vibration acting on an object.

Original Mechanical and more recent Digital accelerometers, used on civil and military aircraft, measure the instantaneous acceleration (or G-force) of an aircraft and its occupants compared to Earth's standard gravitational pull, in units of "G" (e.g., 1G, 2G). They enable pilots to monitor flight conditions, maintain safety, or practice aerobatics or combat maneuvers. Made by different manufacturers, they are offered as non-certified instruments, for use on  experimental and homebuilt aircraft, or certified products, installed on civil transport an military aircraft.

Mechanical accelerometers, included in this listing, use traditional components like proof masses, springs, and damping to measure acceleration based on displacement, offering high accuracy and durability for specific applications like flight stabilization and weapons communication. They are often of larger size and more expensive. Digital accelerometers, separately listed, are often Micromachined Micro-electromechanical (MEMS) systems, integrating sensors with microelectronic circuits for smaller size, lower cost, and high precision, making them ideal for flight stabilization, AHARS, and autopilot systems.

The choice of an accelerometer depends on the application's need for accuracy, size, cost, and resistance to harsh environments. 

Please consult the Product Description section and the supplied documentation for more information on different brands of our offered accelerometers.
