Ferg, I have my single 16 amp hour gas recombinant Odyssey/ Hawker Siddeley
battery mounted on the shelf above passenger feet ahead of the fire wall. It
sits in a fabricated shallow fibreglass tray tied to firewall by a nylon
strap . The multistrand copper #4 leads to the 914 starter and engine ground
are very short and that combination spins the 914 to first time start very
convincingly in any weather. I was and still am very keen on having the
battery forward for efficiency and ease of access, and it has worked
flawlessly x 120 hrs. I am not one bit convinced of the need for a spare
battery. The plane carries on flying without a blink if you switch off
master and alternator switches! A spare hand held GPS seems a better bit of
back up kit. My weight and balance came out alright with this arrangement +
the Kremen C/S prop, although Cof G was more forward than ideal (58.5 ins),
and I ended up putting 3 lbs of lead on the sternpost to get it to what I
felt was ideal position of 59.00 ins. There would be room for two similar
batteries in that position and Bob Harrison has that arrangement with his
Jabiru engine.
Europa give suggested lay outs for fuel lines, and my out and
return fuel lines fit nicely along the top R side of the tunnel ( mono, XS).
The considerable bundle of engine sensor lines run through a single1in. hole
in the firewall to the R of centre to meet upwith the back of my Flydat, but
I don't think there is anything critical about that. Best of luck, David
