The options have changed quite a bit since I started the project,
and the latest iteration has a 180HP and a Hartzell CS prop. I had
already mounted the battery in the normal spot up by the firewall
between the pilot's legs. With all the extra weight up front, I'm
sure I'll have to relocate the battery behind the cabin
somewhere. Of note, however, is that I have electric trim installed
in the Elevator, and the full-swivel tailwheel fork, both of which
add some weight to the far aft location.

Matt,
There should be no problem putting the battery where you first
planned (between your legs). I have the same set up as you (IO-360,
Hartzell C/S) and find the aircraft is perfectly balanced when the
trim is in the center. You will save the nasty problem of running a
heavy wire fore and aft. The low weight AGM batteries are great and
need only minor attention. I would suggest two things: (1) try to set
up a means of charging your battery without removing the center
console, and (2) don't cut through the firewall until you have the
complete engine/firewall forward completed. Yesterday, someone
mentioned that they had a problem working the battery cable around
the exhaust system, and had to "create" a new exhaust hanger system.
I have a similar problem, but not as bad.
It's good to see you so close to home. and I owe you a few years of
contributions. This list, and its manager, is superb. Yea. I know. I
exaggerate a lot.
