Tony, My mono/914/Woodcomp wobbly prop/fully equipped panel set up has the
Odyssey battery sitting over the pax footwell in front of the firewall,
where it sits in a small moulded tray secured by a nylon strap. It left the
C o G in reasonable position, but to achieve what I calculated as the ideal
position, I fitted 3lb lead block in front of the stern post. ( Giving
position 58.96" which allows any combination of pax 150 - 400lbs/baggage
0-80lbs/fuel0-110lbs) I suspect that the saving in extra heavy duty cable.
and support for a rear mounting more or less makes up for the 3 lbs weight
and it is certainly more convenient in the engine department.
So I wouldn't assume that you have a C o G problem, and would be
strongly tempted to plan a forward location until proved otherwise.

Subject: Europa-List: Battery Location with a 914
Gidday,
I have set up a rear battery location for my battery on the assumption that
I will have a CoG problem. I have a 914 with an Airmaster prop, and a normal
panel. Suffice to say, can I presume that I might need weight in the tail
and therefore having the battery back there is a good option, or can I
confidently place it under the baggage bay shelf ? I am about to buy cabling
for the battery which is why I am asking at this point.
If I do keep the aft location I am trying to work out a lightweight
containment that will accept a decent deceleration. The back of my head
looks better without a battery in the back of it. I have thought of using
rudder cable looped aft under the tailwheel leg attachment point, and then
forward onto the battery box. This Odyssey battery at least comes in a metal
battery case. Any input much appreciated.
Thanks
