What expander to run 7.4v?
I am going to run the new Hitec servos designed to run 7.4 volts. I know the servos were meant to run unregulated, but a charged battery is over 8v. Do I still need an expander with a voltage regulator? How high can they adjust?
Plane is a 40% and am going to run 9 of the new Hitec 486 oz @ 7.4.
