I'd recommend you place the BEC and backup guard in the rear to minimize the length of the output wires, and lengthen the input wires. This provides much better performance from the BEC.
Placing the BEC and the Scorpion Backup Guard in the rear is going increase the distance that you must move your batteries forward to compensate for the extra weight behind the main shaft. When running 8S, 10S or 12S this is not a issue due to the length of the pack. When running a large 6S pack I have to locate my battery pack about 1 1/4 inches beyond the front of the frame to obtain the correct forward, aft CG. This doesn't sound like an issue, however, if I move the battery pack much further forward I will be unable to get a battery strap around it. Further, I like to keep switching power regulators (IE: BEC) as far from my radio equipment as possible. The average impedance of a 12" JR heavy duty servo extension with connectors is .001 ohms. The voltage drop across a single 12" extension at 20 amps (CC BEC Pro max) would be 0.02 volts (R x I = V). Connecting both power leads would further reduce the voltage drop to 0.01 volts. Only an oscilloscope is going to see any performance difference from the BEC at a 10mV drop. Since electricity ( not electrons ) travels at the speed of light a 12" extension will not slow down the throttle signal from the ESC to the receiver / FBL unit by any humanly appreciable amount as mentioned else where.
