So my futaba is chattering and I beleive it may be on its last leg. Im new to the RC scene and bought this buggy from a reputable local racer. I understand parts wear out overtime and have no hard feelings for a chattering servo. I would like to stick with Futaba or Hitech as the steering servo in the buggy is a Hitech. I would like to spend around the 100 dollar range.

Also I would like to get a new receiver LIFEPO pack. Any suggestions? Do I still need to run a voltage reg for the life?

And one more thing. The Futaba 3pks it came with I have no idea how to set up. Is there somewhere online that has a quick setup or crash course for using this thing? I understand some of it but am no where near comfortable setting it up.

Thanks!
