    Hi, i am new, i would like to start building the hed but i don´t know if i could use only SG90 servos for eyes and head.

    • There are 2 or three sizes of servo used in the head depending on the version you are building.
      The Official version uses a HS-805BB for the turning left/right as well as a MG996R for the Jaw or equivalent.
      It’s been a while, but I think it also uses 2 x SG90 servos for the eye movement’s
      I’ve built a non standard head, (that comes with it’s own set of problems 🙂 ) using the Dakota76 eyes, it uses 6 of the MG90 servos, but you could us the SG90’s there.
      I still use s of the standard size servos, one for the Jaw and the other for the neck rotate.
      I would not go any smaller for the neck rotate.
