6.0V should not be a problem with any of the standard size Hitec servos. I had used 6.0V for years in all my stuff, a point of reference; I used the unregulated original Duralite Lithium metal cells for a few years without issue as well. I’m onto the new Lithium Ion’s now.

In any event the 4.8V system should be fine with the capacity you noted. The secret is not to let the voltage degrade or become depressed with digitals. A marginally sized system can create an undesirable depressed voltage state under load.

May I suggest when it’s all said and done, you monitor the current draw of each servo and the combined flight system to assure you’re not having issues with binding and voltage depression. Simply stir the sticks as complete system check and look for servos that draw more current than others individually. There are several companies offering inline servo-connector ammeters for our models.

Have fun
