    Mooney Autopilot

    The Mooney has been in development for a number of years, yes. Dynon has limited engineering resources, but the main hold-up is the FAA. Also, the Mooney came after the A36 Bonanza, then the Cessna 182, then a couple of updates to both of those (partially because of an engineering oversight)...

    D10a Digital Airspeed inop

    Make sure you don’t have a kink in your pitot line near the D10A.

    New gremlin and I'm stumped! No trim??

    You lose all of those things when you unplug most likely because the second port on the 2nd screen is probably connected to a hub or something that connects the AP servos, ADAHRS and ARINC. Go on Amazon and buy a male-male 9-pin gender changer and remove the problem screen and tie to two network...

    Skyview not talking back to SL30

    Another benefit of the SL-30 integration is that you can set a bearing point for the active and standby frequencies of the SL-30. That's a great feature when you only have 1 nav radio and want to show 2 VOR's.

    Quick question about GPS175

    You can also use the knob to set the identifier. I agree it's a pain to swipe the keyboard, but using the knob works fine and is arguably better anyway.

    Flap position indicator

    The HDX requires a variable resistance or a 0-5V output to read a sensor like that. I don't know how the 210 flap position indicator works, but if it is a needle gauge (not one that is connected to the flaps with a cable and pulleys, etc.), then it should be able to be connected to show on the...

    Dynon indicates bus voltage when master switch turned off.....

    This is probably some residual/leak-through voltage with no amperage available. If you connected a small DC ight bulb to the bus and ground it would likely pull that voltage down. The Dynon backup battery doesn't power the bus in any way. It powers the screen, ADAHRS, Magnetometer, ARINC...

    A/P Panel and Servo Connections

    You cannot have auto pilot without the auto pilot servos. The trim functionality of the AP Panel is to trim a tab (sounds like this doesn't apply to you) to reduce the force being applied by the servo. The servo controls the actual flight surfaces by connecting to a cable or bell-crank. Just...

    HDX and GNC355 - no glidepath, SL30 - no CRS capability

    I don't know on the GNC355, but the other navigators have an option to Enable VNAV Labels. See if that is an option in the 355. If so, then toggle that to enable and it should fix your problem there.

    Dynon NAV/COMM???

    The form factor of the remote Transponder and Com that Dynon uses from Trig is much different than their panel mounted units, which the TX56A is. If Trig makes one that is intended to mount remotely, then Dynon could, if they see a big enough market, do the same thing as they are doing with the...

    Garmin GPS 175 Installation

    The Dynon should be able to receive in GAMA Format 1 or 3, and it can do high or low speed. You just need to be consistent on all of the speed settings. The G5 may also be able to receive either GAMA Format also. You need to set SID as common for everything unless you have 2 navigators that are...

    Garmin GPS 175 Installation

    It depends on what Garmin GPS. The Intercom will just get Com audio and, if it has an unswitched audio port, it will get audio from the EFIS main harness (gray, brown and black wires). If there is no unswitched audio input, you can use a music port, but realize that it will likely mute the music...

    Installing second HDX screen

    You will splice all of the serial ports with the front screen. You will also need the SV-Network connection. When you get power to the whole system, make sure to do a network detect from the Front (previously existing) screen and it will push all of the settings including serial ports to the...

    ARCINC-429 with GP175 not use serial port?

    The ARINC module gets ARINC429 to and from the 175, but it still needs an RS232 output from the 175 to pin 3 on the ARINC module. The 175 would be set to Aviation output on that serial port. It does not connect to one of the HDX serial ports. This same Aviation output would go to most ELT's as well.

    An update on Dynon Certified projects

    The Garmin servos and the TruTrak servos are dimensionally the same as the Dynon servos. The problem is the approval and the way they connect to the airplane controls. TruTrak has gears internally to increase the torque, and in most cases uses a pushrod connected to a cable or bell...

    Install SV-KNOB-panel

    As long as you have panel space, it is an easy install. If you don't have any open ports for the SV Network, the Knob panel has 2 ports, so it can go inline with any other cable and add to the network. Cutting the panel is the biggest part of the project, but a shop with a CNC can easily do that...

    Wire sizes

    I believe the red and back are 20AWG and the rest are 22AWG.

    GPS-VLOC Auto switch

    To allow the HSI to track the CDI key on the navigator, you have to toggle on the ARINC option "Allow Auto Switch (Label 100P)".

    VOR nav HS34

    I have to say that the suggestion to connect the analog signal from the 430 is not a good fix either. What that really means is something like, "let's spend several hours wiring in a bunch of analog signals to dumb down the functionality of the HSI." Do you have a unit that you can get the...

    VOR nav HS34

    Ron's HS34 is hooked up to the ARINC both on the 530W's VOR output and GPS output. The speed for everything is High except for the 530's GPS ARINC output, which is set to low because of the need to run the TruTrak Sorcerer as well, which will only handle low speed, as I understand it. I don't...
