Spektrum, JR, Hitec and modern Aitronics all use the same connector. Sometimes called a "Z" plug. Airtronics are often blue but are the same connector. The Male version of this plug is universal as it fits Futaba harnesses and receivers. If your flying something modern that's antother brand, nearly every one of these radios will use this plug. Exceptions are micro gear with white plugs. IMPORTANT NOTE: Assembled connectors with enclosed pins are gendered by the shell. A servo or battery end fits inside the RX (or mating plug) and is therefor Male.
2 Wire battery female as found on the battery input lead of a switch harness or the end of a charge cord. This plug will accept the male connector on a stock RX battery pack. Quantity discounts below. SKU Number: RRC2PPFJR

This nifty Y harness invented and available exclusively at Radical RC is handy to use for loaded voltage and current testing of your radio system. Here is what it can help you do:
1. Use in conjunction with an amp meter to test current to any one servo or between the battery pack and the entire system.
2. Use a combo of your amp meter and ESV to see how far your battery voltage is depressing at a given load.
3. Use in combination with our ESV to see what your voltage is while your system switch is on. A jumper plug is used to complete the connection when your doing volt only and no amp tests. Regular hobby battery test and charge cords (you probably already own) can be used to interact with this Y harness.
Here is how is how to use me: To measure current. First set your meter to measure amps and set it one setting higher than you expect to measure so as not to damage your meter. For a typical aircraft you might start at 5 or 10 amps range to be safe. You can reduce the range later (if that is an option) once you know your not going to over drive it. For many digital meters you'll have only two settings, one low like 300mah or less and one for over 300mah up to 10 amps. Use the higher of these two settings for most applications. Unplug the jumper plug. The jumper plug is shown unplugged above at the top of the photo. Plug your JR or Futaba RX charge cord in where the jumper was (notice all black wires here) plug the banana ends of your charge cord into your meter (most meters use standard 4mm banana inputs) correctly. Your meter completes the ground wire connection between your battery and your RX or Servo (or whatever load your checking). Run your device and take your reading.
To measure voltage, Set meter for DC, if it has a set of ranges, choose a lower range like up to 10V (this setting should be above what you expect to measure). Plug the jumper back in and plug your charge cord into the other arm of the Y. Plug the banana plugs from your charge cord into your meters volt check inputs. Take reading.
If you have 2 meters, you can test voltage and amps load at the same instant. Also, with 2 Test Y Harnesses, you can take readings between the battery and also at a distant servo. Maybe you want to know how much voltage drop there is at the end of the line in your tail servos for example. In this case you need to know the loaded voltage at the battery and also at the distant servo to see what the actual drop in your wiring harness's really is. If you only measure at the servo your total voltage drop will be the total of the wiring and the battery and not just the wiring.
Long leg Y harness. Need to drive 2 servos in a tail that are close to each other but far from the receiver? Here is a special part to solve some of those special problems.

The Leg is 6" for all sizes. Arms (to plug servos into) are variable length. Length below is for each arm so 24" Long Arm Y has 48" spread. Size choice is length of each arm from y joint. Pick your size below. 22 gauge heavy duty wire. Note: JR harnesses on left and Futaba J on right. SKU Number: RRCY24A06LJR

This Female plug will accept the common black JR TX battery plug. Use it to build your special charge or cycling harness. The JR T male plug is pictured to right for clairification only. Many views of the Female plug shown.
LOOKING FOR A DEAL? All Futaba, JR-Hitec, Airtronics(old) connectors, male or female & two or three wire single end leads/pigtails are quantity of 5 for $8, regularly $2 each.
This block ended connector will accept any two Futaba/JR/Hitec/New Airtronics Servo ends (male ends). So, It's universal. 4 wires come out of this double female connector block, 1 for "+", 1 "-" battery power (that each servo will share) and one each signal wires (white and yellow) which are independant signal (or control) wires for your two servos. Great if you've got a two servo (flap or spoiler and aileron) wing for your sailplane and wish to have fewer wires to plug in at the field. Many other possible uses where fewer wires are desired to power and control 2 servos indpendantly. Other end of harness is tinned and ready to solder into your harness or project. 24 gauge (between standard and heavy duty) wire. Overall length about 5".
Hint: Solder the two signal wires to one signal out put from your RX and both servos will work in unison.
