We can hand make pigtails to almost any specification. A "Pigtial" has a connector on only one end. Silicone 20 gauge are as heavy as you can get and have the added bonus of being very flexible and heat resistant. Use to repair servos, switch harnesses or perhaps add to existing servos for that "Extension Free" custom instalation. Choose from drop down menus your preferences. Generally we size these by measuring from the back of each connector. So the overall length will be greater by connector shell length. Twisted wire can be adjusted slightly in length by changing the number of twists. We try to get within about 1/2" of your spec. Please order long enough to compensate for minor variance.
10" machine made Silicone pigtails are available in our connector section at lower cost if they can meet your needs.
Note, for a happy life, get your sex right. Servo and battery ends are "MALE", RX's and Y harness receptacles are "FEMALE". When the pins are hidden, connectors are gendered by the shell. Just remember as an assembly, a servo plug fits inside an RX or Extension therefore it's male.
