This is a pack of four pairs of Futaba style servo connectors. Included are four futaba female and four futaba male connector housings and eight sets of connector pins. Also included are four JR style male connectors so you can make up a JR to Futaba lead if desired.
These are unassembled, and can be used to repair a bad servo lead, or to construct your own servo or battery connectors.
