    Another JAVRON Build

    Simple and clean - the new norm in experimental super cub panel design. Garmin & Dynon product lines sure supports this concept.

    This is the panel we have going in our JAVRON widebody build. A big positive shout out to David Buckwalter at Avionics Systems, LLC for his work. I expect I might receive a few replies on the lack of back up. In designing this panel I looked all over the net to find one this simple – No luck.


    Behind the panel on a remote tray. Engine sensor package (GEA-24), ADS-B in / Sirius XM wx/music (GDL-52R), ADS-B out (GDL-82), remote com/3D stereo intercom (GTR-20), remote transponder (GTX-32), 2-axis auto pilot (GSA-2, AOA pitot (GAP-26) all wired through Vertical Power.


    This panel will be connected to a factory new Continental Titan X 370 (200 hp). Still waiting on the crank.


    Plan to provide a follow up post once we get into phase I.

    Nice. Which begs the question I always ask, if that’s all you need/want, why doesn’t anyone create a more minimal panel (surround)?

    Where did you put your circuit breakers?

    I like it. The "Where do I put my beverage?" question is now solved.

    Part of the reason is that the panel is part of the support for the windshield. It stabilizes the whole upper wrap around which is important for reducing the opportunitys for cracks forming in the plexi.

    I would expect the glare shield should be sufficient for that, or could be if designed for it if really needed to stiffen the bottom edge of the plexi.

    There are ways around everything, and I just find it surprising in the experimental world that so few have reconsidered the panel design from 1940, which was designed to fit the fuselage, not for instruments or visibility.

    One of the first things you notice if you turn your engine off so that you can play glider is how much groaning noise the windshields makes at different speeds. It's working the whole time.

    Reference the breaker question.



    This panel is supported by a Vertical Power (VP-X) which eliminates the need to use traditional 1950’s tech (breakers).



    VP-X is a centralized, solid-state control unit that replaces your traditional power bus. This micro-processor controlled unit distributes electrical power to the devices and loads on your aircraft and provides complete circuit protection. Wiring is quicker and less complicated since there is no longer a need to wire through individual breakers, switches or relays, just directly from the VP-X to the load.

    Yes the glare shield does support the windshield base. The instrument panel supports the glare shield. SO. there would be a lot more to it than just shrinking the size of the instrument panel.

    Interesting, thanks. I went with the Garmin recommendation and used breakers for the individual modules. I have lots of breakers and switches, and a crapload of wires, too. I'll read more about the controller you're using. I'm not sure had I known about it earlier if I'd have chosen it. Let's compare notes in a year or so. EXP is fun, eh?

    How do you access your module shelf?

    What's the story on the Titan crank? I had to wait for my Superior engine because they had QC issues with the crank mfg. SAP lost some customers over that. Good luck with yours.

    I'd be interested in hearing more about the GDL-82,
    re installation, and after the airplane is flying re op's.

    The ADS-B units that I'm interested in at this point are the GDL-82 ($1800)
    and the yet-to-be-approved-for-certificated-airplanes uavionix echo for $1400

    I apologize to the OP regarding the thread drift of panel size and design. I like the super clean look.

    Pete, I think you’re splitting hairs here. Anyone building or modifying their experimental airplane probably has sufficient skills to create a new panel design with proper windshield support.
    It takes thought, sure, but it’s not a big or overwhelming thing.

    Looks great. We are pretty close on our build progres for sure
    I have been thinking that it's time to update my thread
    what serial number airframe do you have

    Nifty idea but do some homework before you connect everything to solid state breakers. Some items, such as voltage regulators, use a crowbar circuit as part of the wire protection circuitry. If a crowbar circuit senses something such as over voltage or over current, it creates a dead short which, in turn, causes the external circuit breaker to trip. Old school but very effective. If you connect a unit equipped with a crowbar circuit to a solid state breaker, there is no 'trip'. These 'automatic resetting' breakers in effect limit current flow to their setting. While the crowbar causes the dead short, the solid state breaker does not open but limits current flow to it's setting such as 5 amps.

    There are warnings about this in the Vertical Power installation instructions and in the installation instructions for items such as Plane Power alternators/regulators.

    Works great for what it is intended for, just not a 'one size fits all' deal.

    More of the instrument panel tray complete. Applied hinge material to the bottom shelf to allow for its removal. The back side, on the firewall also has hinge material. Disconnect the plugs, pull two pins and side tray bolts and the complete tray is removable. Will have to remove the G3X panel in order to work on the top shelf. Added two red LED lights to provide cabin floor lighting just below the panel area - on pilots feet.

    I see that you have made the cockpit side of the firewall pretty. I don't know where you live but a lot of heat and noise passes though into the cockpit. You might consider some insulated soundproofing. Aircraft Spruce sells panels for this purpose.

    Skywagon, great catch. Yes we are going to apply the ACS type pad between the two pieces of alum. We have removed the firewall and sent it out for powercoating.

    Also completed the Garmin auto pilot servo install.
    Under the fount seat the servo operates the roll function off the torque tube. Found a quality part to attach to the torque tube. See pic below. A motor cycle light support bracket that connects to the large motor cycle highway crash bars. Just happens be the same size (1.5") as the torque tube. They come in several arm lengths. I found this one on Amazon in the aviation section. The arm rotates along the base with a set screw to allow for a good geometry with the servo arm.

    Mounted the Garmin servo tray to a piece of aluminum and connected straight to the bottom of the seat frame. I prefer servos not be on the floor. Added a few spacers to even up the correct angle with the two arms (servo and torque tube). Once everything is ground tested we will drill a set screw through the torque tube arm and torque tube to prevent any possible movement.

    Placed the pitch servo in the tail. Did so for two reasons. Accessibility. Simply remove the bottom tail panel (which you do during every conditional) and there she is for service as required. Second - cable slack. Mounting the pitch servo this close to the elevator removes nearly ten feet of possible cable flex which causes the servo to continually play catch up.

    Progress is measured in a number of ways. Was down for about a month -but back at it now.

    You have a low spot in the fuel line running to the rear fitting in the fuel valve. This will collect water much like a sump. This line needs to feed the T from the top, not the bottom. The tubing bends look excellent so with that kind of skills it should be a easy job to make it right. Very nice plane!!
