I just bought a new Savox Servo which is high voltage 7.4 says. It's the SB 2290 SG. I know it's probably Overkill but I wanted to get a real good one that's being my first replacement. I've never programmed one of these. So my first question is do I need to program it? Zecondly how do I program it if I do? I have the Spektrum dx3 radio. Third question is do I plug it right into the receiver box or does this need its own feed from the battery?
