Is there some reason not to run 4.8 volt system? I am building my 28% Edge with 8611a on rudder and 5945's on the other flight surfaces. I would like to stay with 4.8 only because my other planes are 4.8 volts. I was thinking with the torque of these servos, 4.8 volts would surfice. It just has me wondering since it seems that everyone else is running 6.0 volt. I do plan to run dual batteries on the receiver.
