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).

UMA airspeed indicators are fully FAA TSO'd to C2d specifications for installation on certified aircraft. Installable in a fixed wing aircraft with a reciprocating or turboprop engine. Must be installed in a temperature controlled environment form -55 to 85°C, to a max altitude of 25,000 ft. These airspeed indicators are available in different versions, 2-1/4",Single Speed MPH and 3-1/8" single or dual scale (MPH/Knots) versions with an outside/Inside scale: 40-200 MPH/40-170 Knots, housed in a Valox 420 Plastic case and weighting 8.6 oz. They are offered with or without certification. ASI markings are sold separately for each unit at additional cost. Please select the markings option if markings are required. 

4-Pin connector by AMPHENOL for use in all electrical gyros (DG or Horizon) including Falcon models.

The FAA TSO'd RCA26AK (14V) and 26BK (28V) series of electric attitude indicators (artificial horizons) by KELLY MFG (RC ALLEN) are known for their dependability and ruggedness. They incorporate tremendous advances in presentation, precision, and reliability.With a proven track record for dependability and ruggedness, the attractive new extended color schemes and ultra-precise spherical presentation (eliminating old parallax problems) they set a new standard for safety.These gyros provide a more accurate IFR reference for the beginning instrument pilot or a Cat II captain. A new three phase motor/inverter is designed into the gyro enabling it to operate at lower temperatures which extends to useful life. The instruments employ a new, high precision air erection system which provide erection torque for maintaining a proper vertical alignment reference. The erection air is supplied by a turbine pump which is integrally coupled with the gyro motor. Through maximum utilization of unitized construction the design is free of resonant frequencies below 100 HZ and thus cannot respond to low frequency disturbances which can cause dither and premature wear out of the unit. The display portion of the instruments has a directly coupled roll movement, and a pitch movement mechanism identical to that of the field proven vacuum gyros produced by R.C.Allen since 1966. A "pull to cage" spring type force limited mechanism assures immediate alignment and stability whenever power has been applied to the gyro, a feature non-existent on vacuum driven gyros. These artificial horizons have a hybrid inverter which converts the aircraft DC power to the required voltage and frequency for motor operation. All units have a pull cage knob and a power failure flag that drops into view whenever the supply voltage is lost or when the voltage has dropped below a level of acceptable for proper operation of the gyro. Slip indicator can be added to satisfy FAA AC91-75 upon request. Available in 14V or 28V voltage versions with fixed or movable pointer, lighted or unlighted, power failure flag, panel tilt and optional inclinometer. Mating connector MS3116E8-4S and panel screws are now included with each new instrument at no extra charge.

HONEYWELL BENDIX KING® KI-229 Radio Magnetic Indicator (RMI) provides bearing information to either ADF or VOR stations by means of two pointers each of which is read against compass card.

The KI-229 RMI combines three data points on one indicator. The current aircraft heading from an HSI is shown on the card. The magnetic headings to VOR and NDB stations are shown by the twin needles. By combining all this information visually, less interpretation is required thus enhancing overall situational awareness, something especially helpful when the workload is high.

The KI-229 requires inputs from ADF, HSI and NAV receivers.

The HONEYWELL BENDIX KING® KMT 112 is a Magnetic Azimuth Transmitter (aka Flux Detector or  Valve) which senses the direction of the earth’s magnetic field and continuously transmits this information through the slaving circuitry to a directional gyro (such as the HONEYWELL BENDIX KING® KG 102A or KSG 105 slaved directional gyros). This sensor is mounted remotely, usually in a wingtip, to eliminate the possibility of magnetic interference. The KMT 112 is typically used in HONEYWELL BENDIX KING® KCS 55A and KCS 305 compass systems. The KMT-112 flux valve is a sealed unit and cannot be serviced or have parts replaced. The unit must be replaced when/if it fails.

Like other KCS 55A compass system components, the  KMT 112 transmitter can be furnished in NEW condition or as USED in Serviceable or Overhauled conditions indicated respectively by the letters "SV" and "OH" in the product reference numbers (SKU and  accompanied by the relevant certification (e.g. yellow tag, 8130-3 form). They are also offered as exchanges / trade-ins  for returned customer owned units indicated by the letter "EX" in the SKU.  In the case of an exchange/trade-in option of a customer unit, the  full selling price of the ordered unit is charged and the core credit is refunded or credited towards future orders when our co-operating supplier verifies that the unit is in a reasonable, repairable condition. It is recommended that this option is selected by our customers mainly for upgrades and only in cases when their units are functioning properly at the time removal from the aircraft. In cases when customer units are found by our supplier to be non-repairable, the core deposit shall not be refunded and shipping charges shall apply if customers wish the return of these units to them.
