Right but a freshly charged 2S A123 pack can be anywhere from 7.2 to 7.4 volts; sure the voltage drops as soon as the battery is under load, but its still above 6.6 volts for a good portion of its charge...with NiMh, the surface charge drops considerably faster; fresh off the charger, 6.8 - 7.2 volts depending on the rate of charge, but under load it quickly drops to 6 -6.2 volts... not saying the servos couldn't handle the s2 A123 voltage under normal flying conditions, but the voltage is the push behind the current and the higher the initial voltage is, the higher the current draw will be by the device... would be nice to go all A123 though, maybe I'll experiment and see how a couple servos handle it... or I can switch to HV servos, but to put HV servos in a sport aircraft, is just a waste of money for me personally,
