Carl,
I measured right up against the center pod, Used a CG stand and flipped the bird upside down.
If you are using the included gear you're good to go. If you use retracts, see how much the CG changes when the gear goes up.

Cooling "inlets" are needed, and don't forget some exhaust ones too, gotta let the air out.

My packs sit up under the main canopy, I get airflow for them from the nose gear opening, and I have the canopy sit not quite flush at the rear, to let the air escape.
I also opened up the intakes on the fiberglass motor cowls to cool the motors, air gets out the rear through the landing gear openings.

Make sure you have lots of runway, and don't try and horse her off the ground. She'll let you know when she's ready.
And she will come in fast on landing. So be prepared.

Best of luck.
