RE: electronic Jitters?!!?!
First, make sure everything is plugged in correctly. Make sure both recevier and transmitter are on the same channel. Make sure the receiver has an "F" sticker on it, not a J. A "J" means it's the JR/Airtronics version, and won't work with your Hitec transmitter.
Beyond that, the only other thing you can do is start switching things out, one at a time, to see which piece is faulty. It might be a bad transmitter, receiver, servo, or ESC.
