Bob,
Behind the seat for the pump and firewall for the battery will almost
certainly work out well balance wise. A 320 with a CG too far forward would be
extremely rare. Keep the weigh forward. You will be glad you did.

Bill,
Just curious, where did your battery and hydraulic pump end up? I
have same configuration, except for 3 blade MT prop and have been considering
behind the seat for the pump and firewall for the battery! ( not yet
weighed for cg )
