Default Built-in Oxygen System for RV8?

Any -8 builders out there have advice on how you installed your oxygen system? Pics would be a bonus!

I very early in my new -1 slow build fuselage, but I thought I'd start gathering some data.

Thanks in advance!

Interest here also. I'd ike a semi-permanent installation, bottle in baggage area (not always there) , plumbing to instrument panel, quick-disconnects and flow-rate meter & adj. per pilot & passenger.
Are there any sources for parts to do this?

I'm no builder, yet..... but I would look into glider oxygen system installs. They're compact, and some panel mounts like what you were looking for. Very common in the soaring world to have an aircraft O2 equipt.

Brent,

These links are RV-10 specific, but may give you some ideas.

Default O2

I added a floor rib between bulkheads aft of the elevator bellcrank. I used that rib to mount my S-Tec pitch servo bracket and my O2 bottle. I run high pressure lines to the O2 regulator up near the instrument panel. I mounted the flow valve on side panels near the 804 bulkhead and have a pressure gauge on the right sub-instrument panel. The refill station is mounted on the longeron gusset just behind the passenger seat bulkhead. I've attached a few pictures.






However, if I were to do it again I would opt for a semi-permanent mounting solution. I have a good friend who did this with his -4. He mounted his tank in the baggage compartment directly behind the passenger seat perpendicular to the longitudinal axis. The regulator is mounted to the bottle. From the regulator he permanently runs low pressure lines to the pilot and passenger locations. Operationally, if he anticipates using O2 he simply opens the valve on the regulator before he takes off. O2 will flow to the breathing station bulhead connectors but it won't deliver O2 unless the cannula or face mask is connected. Mountain high also offers some remote regulator options that allow in-flight control of the regultor. This arrangement is nice because you can easily remove the bottle for filling or if you don't intend to use O2 on a particular flight.

Default Perfect!

Rick,
That's exactly what I was looking for. Thanks a bunch!

Anyone else have a built-in RV-8 system they can share? It would be nice to see a couple of versions.

Regards,

Default Oxygen systems

I want to install an oxygen system in my 8 and wonder if anyone has experience and recommendations to share.

I use a small portable Sky OX unit pretty regularly on XC missions these days as my plane is way more efficent up high. It works very well, though I don't have experience with other brands to compare. I have had it since the early 90's and it has held up well.

I am a firm belever in keeping the plane as light as possible for any given mission, so I did not want to install anything permanent since on most hops I will not carry OX. I see no real downside to leaving it portable.

Default O-2

I installed a removable bottle in the aft cargo compartment and ran lines forward on the right side. I installed doublers in the floor and added Nut-Serts AKA Riv-nuts for the tie-down clamp bolts. If you do this before installing the aft cargo comp. floor, you can add doublers and regular nut plates.

I'm not a kid anymore, so I use O-2 anytime above 10K. If I'm going into the flight levels, I pre-breathe while climbing to increase oxygen saturation. This is a procedure we used when I was in the Military when we needed to work with the cabin de-pressurized. Oxygen is cheap, so there's no reason not to add it to your plane.

The system is totally removable and well worth the effort.

Default Pulse Demand delivery systems

I would suggest the Mountain High pulse-demand system. It reduces oxygen consumption dramatically so you can use a smaller, lighter cylinder and/or not refill as often. This description came from their website http://www.mhoxygen.com/
The EDS O2D2, with the patented digital electronic "Pulse Demand" oxygen delivery system, enables the pilot and passenger to fly at pressure altitudes up to 25,000 ft. with safety and comfort. The EDS O2D2 digital pulse demand system reduces oxygen consumption dramatically. Different from the "standard" constant flow systems, the EDS O2D2 pulse demand system wastes no oxygen during the breathing cycle when oxygen is not being delivered to the lungs. The average user will enjoy a conservative consumption drop of 4 times compared to the constant flow systems. The system operates with two people for up to 50 hours on three AA alkaline batteries.
I have not used this system myself, but I have heard nothing but positive comments from a number of sailplane pilots I know that are using the MH system.
