Could anyone suggest a best practise for powering an ArduPilot Mega please?

I have a quadcopter project
The APM is mated with an OilPan IMU (diy drones)
I have a 7.4v lipoly which will be powering my spektrum receiver - and the six outputs from the receiver are connected to the AMU.

The esc's for the motors are powered by a separate 11.v lipoly pack - the power lead between the esc and APM is removed (ie the esc's send no power to the APM).

Will the APM/OilPan IMU take power from the receiver connections? If so do i need to regulate the 7.4v (to 6v) before connection to the receiver?
