is it possible to run 7.4v to one servo and just 6v to the other?

The HV servos were born from the rock crawler crowd, and they generally power the servo directly off a 2s lipo pack and use a BEC to give 6v to the rest of the electronics.
So, if you run a 2s receiver pack you could power your HV servo and then use your new BEC to power everything else. (BEC paralleled to the HV servo off the 2s)
To directly power the HV servo just run the + and -of the receiver plug directly to thhe 2s pack. Run the third wire (the signal wire) in the receiver plug to the receiver like normal.
