| Jim began building the RV-10 kit in 2008 and finished in in 2025. Although the aircraft is equipped with the Lycoming iO540 and not turbo charged cross-country travel is a regular occurrence for this workhorse since it started flying. The Twin Turbo O2i system has been the latest upgrade. |

Mounting the Turbo unit 1 and 2 in the empennage
The tail cone area was chosen as the location for installing the Twin Turbo O2i units. This is a Left and Right Configuration. Left unit, Turbo 1, (pictured right) services pilot and passenger behind pilot and Right unit, Turbo 2, (pictured left) services co-pilot and passenger behind co-pilot. This configuration allows maximum ceiling for 2 users to 18K.
Because the units were not installed on a wall panel custom aluminum panels were fabricated to mount the Turbos to the tail cone stiffeners. Shown here one from the font side and one from the back side.
The mounting plate is riveted to the stiffeners with the T-mount and J-mount attached with the included mounting screws. Once the Turbo is placed on the J-channel a third mounting screw secures the Turbo to the panel plate and T-Mount underneath.
Routing Tubing Left Side and Right Side
Left Turbo Tubing is routed to the pilot position, using a cannula quick connect bulkhead w/o check valve.
This same left unit tubing is diverted equidistant to the passenger behind the side panel. This passenger port has a check-valve. An elbow fitting is added here to the bend in the tubing.
Passenger behind pilot panel with Aithre Dual USB Port Cannula quick connect with check-valve. Behind the panel is visible the tubing connection to the barb.
Tubing is routed along the rear seat panel back to the Turbo 1 unit using plastic gromets for drilled holes; bulkhead push to connect connectors can also be used.
Grommet used in rough panel cut hole. Tubing guide used to mount against the seat wall.
Labeling the tubing when routing back to the tail cone is a good idea for future reference.
Right side Turbo unit plumbing routed to the co-pilot connection on the avionics panel.
This quick connect is the pilot #1 position on the Right side Turbo unit and the quick connect has no check-valve. This becomes the copilot cannula port.
Right side Turbo tubing split from co-pilot to passenger behind co-pilot, keeping the 2 lines approximately equidistant.
Right side Turbo passenger behind co-pilot output cannula quick connect. This quick connect fitting has a check-valve.
Connecting Turbo 1 and Turbo 2 to Bottle and Cannula Tubing
Turbo 1 on the Pilot side. Note the red heat sheathing on the "in" line from the bottle. This is high 50-60 PSI pressure and high flow from the bottle. Blue tubing "out" line is tubing directed to pilot and passenger behind pilot cannula bulkheads.
Turbo 2 on the co-pilot side of the aircraft and closest to the bottle connection. Note the red heat sheeting on the "in" line from the bottle and tee split ready to connect to Turbo 1.
Tubing line routed to the bottle is covered with heat sheathing through bulkhead frame. Blue lines are "out" tubing originating from Turbo 1 and Turbo 2 routed as previously shown to cannula quick connects at the stations. The Meso wiring from bottle tank pressure sensor routing to Turbo 1 is shown bundled with Turbo 1 and Turbo 2 communication wires. Note that bulkhead push to connect fittings can be used here or grommets over cut holes as in this example.
Blue tubing continues along and behind the baggage panel through rear seat support spar. Heat sheathed bottle connection tubing routed to rear seat horizontal spar where bottle is mounted and connected.
925L bottle shown mounted with bottle straps to horizontal rear seat spar. Meso tank sensor wiring and male M8 plug also mounted to spar.
Close-up of grommets in holes (from previous installation) and quick-connect used for bottle connection to Turbo connecting tubing lines.
Closer detail of bottle and Meso tank sensor connections.
Power On/Off Buttons
Previous panel cutouts covered with overlay panel for Turbo O2 "on/off" buttons. Left button for left (pilot side unit) and right button for right unit (copilot side unit). Blue light indication unit is on.
Avionics Connections
Because this plane is the also the Aithre test plane it is equipped with all versions of the HealthView I, II, and III avionics and ATD-11, ATD-57 as well as the ATD-Radio.
The remote mounted ATD-11 in a vertical orientation is shown with the HealthView II. HealthView I can be seen mounted on a fabricated throttle panel.
HealthView III initially mounted for testing (later to be permanently wired and mounted behind the panel. DSub 15HD connector used between HealthView III and ATD-57 (pictured below).
DSub 26HD used to connect HealthView III to Turbo 1, Turbo 2, Illyrian Hardwired Connectors (2), Metis wingtip weather beacon, CO Sensor is in the HealthView III unit. this is the data bridge to the ATD.
Illyrian hardwire connector connected ready for throttle panel mounting.
Illyrian hardwired connectors are mounted to throttle panel with placards. Pilot top plug, co-pilot bottom plug. Note 2nd ATD-57 installed with split signal and shared data to avionics panel mounted ATD-57. eDot light mounted to throttle panel and CO data output from HealthView III to ATD and the panel LED. Note Metis also directly connected to HealthView III with output to ATD in both locations.
Pilot Illyrian II plugged in receiving instantaneous data output to ATD (both) via the hardwired micro USB connection. Note the CO LED output indicator.
System Output
HealthView II ATD-11 outputting AVI data, CO from EX 3.0, Bottle O2 PSI, Pilot HR, SPO2. Dosage control of AVI (or Turbo) can be controlled using the ATD.
HealthView I also outputting system data.
Previously installed Metis wingtip weather sensor installed on underside inspection panel on right wing.
Metis communicates weather via BLE data to the HealthView I and II via ATD-57 or ATD-11. Metis sensor has now been connected to the HealthView III which directly outputs data to the ATD-57 via DSub wire, eliminating wireless communication.
Twin Turbo System Testing In-Flight
Turbo 1 is on and outputting 1.4 LPM combined with .2LPM of injected flow from the bottle for a combined output of 1.6LPM. Note that if only one user is plugged into the system (via cannula port) all the flow goes to that user, in this case pilot. If 2 users are plugged in, pilot and passenger behind pilot then this total flow is split between the 2 users. (It would not indicate on the ATD that the flow was split).
This screen shows adjusting the injection flow (when on) using the dial.
Turbo 2 is turned on but injection currently off. This ATD page is configured to show Turbo 2 data output.
This ATD page is configured to show pilot station data from the Turbo 1 and pilot biometric data from the Illyrian II hardwired connection.
This ATD page is configured to show Turbo 2 output data. Copilot or pax1 is using Turbo 2 and biometric data is displayed here although copilot was not wearing an Illyrian so data was not available.
This ATD output page is configured to show Metis weather beacon data including cloud and freezing level estimates.
This ADT page is configured to output the Shield carbon monoxide and cabin temperature and Metis data.
