The RAC RP3 LED Position Indicator (Elev 2) is a cockpit-mounted 10-LED position display used to indicate the real-time position of an elevator trim servo or elevator position sensor system. It is part of the Ray Allen trim indication system and provides visual feedback of actuator travel for pitch trim control.

The unit uses a linear 10-segment LED bar display, driven by a position sensor or compatible servo system. As the elevator trim actuator moves, the LEDs illuminate sequentially, showing direction and magnitude of movement to the pilot.

The “Elev 2” configuration typically refers to an alternate calibration or second-channel elevator trim setup, depending on aircraft installation, while maintaining the same RP3 hardware format.

It is commonly installed in experimental and light aircraft trim systems, paired with Ray Allen servo actuators and position sensors. The unit is dimmable for night operations and designed for standard panel mounting.
