Good information Chad. My reason for mentioning the peak voltage is that if someone has servos that are above the maximum voltage at 6.66 volts then the 7.2 volts might cook them. I am using all Futaba digital servos tied to a Smart Fly power expander in our 42% Super Decathlon and have encountered no problem. Of course, the Smart Fly provides regulated voltage for the receiver. The ailerons are fed through a Futaba MSA-10 equalizer.
