Putting servos in a schwing, KST 125MG in the wing (not HV) and Savox SH-255 for elevator and rudder. Both types of servos are rated at 6V with Savox saying they will take up to 6.7V load and 7.4V no load. Want to run these off a 5 cell 2/3AF pack so 6V nominal, but we all know it will be higher. Any experience on this set up or even running a 6.6v LiFe pack?
