over volting servos

[_paralyzed_]

I have two very slow cirrus cs-80 servos on my e-maxx and I want to run them at like 7.5 volts to speed them up via a cc bec. Can I just pull the power wires to the servos and wire them directly to the cc bec, leaving the signal wire in the reciever, so as to use the internal bec on my mmm to power the receiver only and the cc bec to directly power the servos? Is this possible, or am I way off?
