RG35AXC Weight and Balance

[Steve65E-NC]

    I have just purchased a Concorde RG35AXC for my 1965E and will need to revise my W&B for the extra 2.5 lb.  Can someone give me the official moment arm from datum for the rear mounted Battery Box in my, short body, aircraft?

     Any other items to consider in this change to an AGM like maybe adjusting the alternator regulator voltage.  Concorde give a bunch of Voltages for a variety of temps.  What are others using?

According to this, the ARM is 105.8:

Dustin,

    Thanks.  I looked and I have the same pages in my POH.  Could have just measured from the nose gear attach datum to the battery box behind the luggage area in the rear,  but better to have something official.

    What did you use for the voltage regulator set point and how do you charge yours.  My standard auto charger has an AGM setting and I plan to use that?  I know Concorde talks about special chargers  but the trail just leads around in expensive circles.

Steve-You are going to really like the Concorde. I had a couple Gill batteries with service and charging prior to install of RG-35AXC on 2/23/08. No supplemental charging or significant service since install...and still going strong.

According to the type certificate page 21, the battery is located at station +105.8
