RE: HELP!: Making a circuit so that a 7.2v batt produces 6v
A dropping resistor works only when the current is constant, and servos draw a few mils at rest and much more when moving and working.
What you need is an IC voltage regulator - MC7806 - which will supply 6V regardless of load. It is a simple three pin device: In, Out, Ground. Luck mate, Eloy
