Finishing AC hose routing, Evaporator shelf, front baffle “walls”, interior panels, and test fitting panel.

I finished up the routing of the AC hoses down the right side of the fuselage. The hose going all the way to the tailcone dives down towards the floor and goes through the bottom most lightning hole to make sure it doesn’t interfere with the flap tube in the next bay aft. I placed a small piece of angle on the angle attached to the side skin, used nut plates to screw the 2 angles together and then utilized a nut plate to keep the hose from rubbing on the angle attached to the skin.

View of the metal piece riveted in all 4 corners of the lowest lighting hole with a bushing through the center for the hose to pass through.

The hose destined for the condenser scoop, goes across the flap tube area on it’s way across the tunnel and to the 1st bay under the left-most rear seat.

Hose continuing to the tailcone under the right rear seat.

I utilized Adel clamps anchored to the step to route the hose inward and keep it away from the bolt holding the step in place. It then makes its way aft to the tailcone.

Similar for the hose going from the condenser to the tailcone.

With the hoses done short of crimping on the ends, I started working on the evaporator shelf by using cardboard as a template.

I test fit the cardboard until it was trimmed correctly to sit between the longerons.

I then used the cardboard to mark up the fiberglass shelf and trimmed it, sanding a little bit to get a good fit. Shown here as well are the 3 holes matched drilled into the shelf brackets that get riveted to the longerons.

One other small task was to trim the upper cowl ramps and add a “wall” so that the baffle material could sit in-between the upper air ramp and this “wall” so it has something to push against.

Using some scrap fiberglass to trim up a “wall”

I then mixed up some flox and bonded the “wall” in place with a small “D” shaped piece to provide support against the cowl wall. This was repeated for the other side.

One nice day, I decided to head outside and paint the interior panels. I ordered the lighter tan ones knowing that I was going to paint them a darker color. I think they came out nice!

I ran into a snag with continuing with the evaporator install so I worked on completing disassembling the panel. I removed the wiring harness and separated the metal sub frame of the panel from the carbon fiber.

Wiring Harness removed
Carbon fiber panel with avionics trays.
Metal subframe with shelf for various components.

I spent some time getting the metal subframe in place, followed by the carbon fiber panel with the avionics trays. This first test fit was mostly done to mark the sub panel where I’ll need to cut away and reinforce making room for the connectors on the back of the 650 etc.. Not a whole lot needs to be removed just a small rectangle near the bottom and really just for the connectors and so the wiring harness doesn’t get bent too much.

Panel has arrived

It’s really exiting to have the last major piece of the puzzle in hand.. There is still so much to finish up…, but it’s encouraging and helps me to keep grinding away towards completion.

To recap the configuration:

  • Triple Garmin 3GX touch screens
  • GTN650 IFR Navigator
  • Dual GSU25 ADAHRS
  • G5 Backup Attitude Indicator
  • GMC507 Autopilot Head
  • GMA245 Audio Panel
  • GEA24 EIS (Engine monitoring)
  • GTR20 Remote COM (COM2)
  • GTX45 Remote Transponder
  • SDS EFII Controller
  • Mountain High EDS-4ip 4 place oxygen controller. 
  • GDL-51R Remote Sirius XM receiver

Stick grips came in the package as well all wired up and ready for me to connect. I went with the Infinity HOS (Hands on Stick) Military style grips. Several controls are on the stick that might otherwise be on the panel. The idea here is to have both hands on the controls and throttle during critical phases of flight; not having to move them to activate flaps, for instance.

Here’s a rundown of the button assignment:

  • High hat in the center to control roll and pitch trim.
  • A switch on the thumb side to control the flaps. This is a momentary down to advance the flaps electronically to the next “notch” and a constant up position so the flaps are raised all the way up.
  • Opposite of the flap control, there is a Take off/Go Around button. This will sequence the autopilot/GPS to the missed approach segment when needed.
  • The Red button on the thumb side is a Auto pilot disconnect/control wheel steering button.
  • And finally a frequency flip-flop button. I didn’t really know what to add to this button, but decided on this.. Some people do ident, start button, or other functions. We’ll see how useful this ends up being in practice.. Guess if doing instrument approaches etc.. I may be setting up next frequencies in the standby area ahead of time enough to just have to hit a button with my pinkie to switch when needed.. We’ll see..

And finally some pictures of all the wiring between all the components. Along with several P-Plug connectors on either side of the panel for me to connect to all the other locations in the plane. Aerotronics mounts as many of the sub components right to the panel, as you can see. This alleviates me from having to mount them on my sub panel. Of course all the wiring harnesses are also already all done for me. Including runs out to the wings for AP servos and magnetometer, along with runs to the back for AP servos and trim servos back there. Lots and lots of wiring ahead..

And finally a picture of my panel from Aerotronics all powered up and tested prior to shipment.

They have been really great to work with.

More panel pics

Just a quick update with some additional pics of the backside of my panel in progress at Aerotronics.

Probably a couple more weeks before it’s ready to ship.

Note the switch pod up high
A nice closeup of the shelves that house most of the subcomponents including the FlyLED controller.

Initial Panel Rendering

After a bunch of back and forth with Aerotronics, we have a first pass rendering of the instrument panel. They have been absolutely great to work with thus far.
