These are standard servo "Y" cables, and feature the brown/orange/yellow wire colors and connectors that are common for JR and Spektrum radios systems.  The connectors are the "universal" JR/Spektrum type, in which the male (larger) connectors are slightly thinner than the Futaba type, allowing them to plug in side-by-side into smaller receivers without interfering with one another.  The male connectors DO NOT have the Futaba tab opening, but they are beveled on the top, which provides the necessary polarity, and prevents them from being plugged together incorrectly.  The female (smaller) connectors DO NOT have the Futaba tab, and are also beveled on the top for proper polarity.
 
These cables are made with 22AWG silicone cable (the largest cable that will fit into the plastic housing of a servo connector).
 
For now they are only avaible in 6" length, but more sizes are coming soon, so check back often for sizes you need that are not yet offered, or Contact Us and let us know what you need, we'll try to get them.
