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:

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.

 

Thanks so much, 

William Ford
