I mounted my bottle in the middle of baggage compartment attached to flap support channel. Inran the tubing down the left top fuselage stringer to the panel and mounted my controller under the panel just to the left of the throttle cluster.
The tubing supplied in my kit was only long enough to put the controller between the seats to the rear of fuel valve. But here the controller is upside down and the control face cant be seen. So I ordered extra supply tubing and moved it to panel. Much better location.
Interesting mounting idea. Is there a limit on how long the hose from the bottle can be?
My tank is mounted to the same location and I just attached the O2D2 on top of the horizontal/backseat support next to the bottle itself with the two velcro strip that came with it. They are both usually removed and I mount them only for travel times. At this location, the hoses are not in the way and I have easy access to turn it ON/OFF etc.I mounted my bottle in the middle of baggage compartment attached to flap support channel.
Bottle behind the pax seat, on top of the right RV bag.
The control panel on the bulkhead between the seatbacks, facing forward. It is secured using 3M dual lock, and has resisted all my bounces and botched aeros, until now that is
Not sure what you guys in the US call it, but it is a 2 liter for me. Since I only use O2 occasionally during solo flights, the bottle usually lasts a year. As it’s just a rental, a trip to the shop for an exchange is quickly done.
