Hi William –
Welcome to the LML! I also omitted the
floorboards in my Legacy RG to increase the baggage space. I put my pitot tube,
landing light, and strobe light power supply in the right wing stub, leaving
the left wing stub wide open (and incidentally freeing that area of all electrical
components). I was then able to fit a Mountain High AL-415
(14.6 cubic foot tank) in the left wing root. The tank’s dimensions allow
it to be removed through the foot well area of the cockpit for inspection and
service. Now that my wing stub is closed, the hold-down clamps are accessible
through two access panels – one by the pilot’s left foot and the other
on the underside outboard end of the wing stub.
My only regret is that I could have used a
much larger tank. Making a 4.5” diameter hole in the wing stub’s outboard
rib would have let me install the AL-682 (24 cubic foot) tank. That would mean
pulling the left wing in order to remove the tank, but that’s only once
every 5(?) years for inspection, which would be acceptable to me.
Here’s a photo of the tank
installation before I closed the wing:

Subject: Oxygen tank location
To introduce myself: My name is William Ford. I've been
enjoying everyone's posts for a while now, but have not posted myself until
now. About nine years ago I bought my Legacy RG kit. Its been a
long road but hope to fly it this summer (before the 10 year anniversary!!!)
I started the project in SoCal and am now in Durango, CO.
My plan, as it now is, is to NOT install the factory floor board
system. That being the case, I'm considering alternate locations for the
O2 tank. At the top of my list of options is in the tail cone, mounted to
a custom shelf/bracket system on the right side of fuselage just
above(supported in part by) the pitch servo bulkhead. The concern I have,
and the feed back I'm looking for, is regarding the potential ignition source
from the battery and relays that are also located in that area (according to
the origional plans). Could any of these electrical components produce
arcing??? Could the MH cylinder/valve/fittings possibly leak, producing
an explosive mixture??? I suppose the battery and relays could be
relocated. Are there any thoughts about putting the battery directly behind the
pilot seat, up close to the aft spar??? Heck, why not redesign the
whole airplane?
So, what is the consensus of the readership? Are these concerns
"over the top"? Perhaps the reply will be: Whats the big
deal, we're already carrying a bomb in each wing...why not throw one in the
tail too. All kidding aside, I am seriously interested in any
thoughts or suggestions.
Moving to the airport REALLY soon.
