These are the servos used in our Chassis. The servos are made by Hitec. For Details see the datasheet. On all Hitec servos the Black wire is 'ground', the Red wire (center wire) is 'power', and the yellow (third) wire is 'signal'. This servo has a Hitec/JR connector which mates directly with a 0.1" 3-pin header. This servo comes with mounting hardware, servo arms, and rubber mounting grommets.
To mount this servo to a flat surface see our servo hardware kit. We also sell scanner brackets (Single or Dual) to attach to the servos.
If you'd like a servo with continuous rotation, please see HSR-1425C.
