    Replacement for EFIS D10A as Backup for Skyview system

    I have exactly that - a Garmin G5 with a dual 10" HDX, dual ADAHRS system. The G5 is so superior to (and so much cheaper than) the D10A that even if the D10A was available, there would be no reason to use it. Plus, with the G5, there can not even be the hint of a common mode failure in either...

    Radio troubleshooting + squelch question

    Probably an antenna issue. If you're flying a Lancair 360 (which I gather from your forum name), then you'll need to investigate what's being used for an antenna in a composite plane. In my COZY MKIV, using Jim Weir's $5 copper tape dipoles, I can receive/transmit to stations/aircraft 100 - 150...

    Oil Temp Overheating

    What airplane? What engine? What transducer? What units for OT, CHT and EGT?

    VSR on HDX

    When using an external Navigation source (I have a Garmin 175), the VSR will NOT display on the Skyview. I've reported this as a bug to Dynon, but, well, it's not like they have an official bug reporting system, or a Defect Tracking System, or anyway of checking up on how bug reports are being...

    C182R Install - Joining the Blank Panel Club

    Emagair products are not certified or STC'd for TC'd aircraft. Experimental only, per their web pages and instructions.

    Reclock Servo Arm?

    Grab the arm and turn the shaft until it points in the direction you want. You won't hurt the servo. Maybe I'm not understanding what you're asking...

    manifold pressure / CHT pickup

    CHT probes never attach to primer or injector ports, so these are orthogonal questions. Pull MP from one of the ports mentioned, or from a port you put in your intake ducting above the carb/FI servo. Generally, Lycomings will have a CHT threaded well on the bottom of the cylinder into which you...

    Heading Bug Reprogramming...PLEASE

    I have no idea if there are any other A/P's that can do what's requested here, and there may very well be none. However, given the existing software inside the Skyview system, it would be a trivial amount of work to achieve this end - just tell the system to turn in the direction that the last...

    Need advice about adding radios to HDX

    PS makes a combination Audio Panel and COM radio (PAR200B). If you're going to have two radios (I don't know why folks believe they need two radios any more, since almost all decent radios, including the Dynon/Trig radio, can monitor a backup frequency, but personal preference, I suppose) then...

    Calibrating Oil Temperature sensor

    The OT sensor can't be "calibrated", but it can be checked - just did exactly that on the single wire sensor on a Long-EZ this morning. Heat up a pot of engine oil to 300F and buy a candy thermometer (be VERY careful - the last thing you want to do is spill 300F motor oil on you or your...

    Compass cal / winds aloft error

    So magnetometers in the cockpit tend to be problematic - I might try moving it to the tailcone, up as high as possible to get it away from control pushrods and cables, as well as the wiring down low. If the PMAG's are putting out EMI/RFI, and feeding that into the main wiring, getting the...

    Compass cal / winds aloft error

    So you didn't say where the adahrs is or where the magentometer is in your plane. Might be useful to know (or might not...). I've installed both Dynon and Garmin systems in many composite planes, and there's no reason that the magnetometer can't be accurate to within a few degrees (mine is, for...

    System32 EFII RPM & Dynon HDX

    Glad you got it working. While a tach signal is not a safety critical item, I'd still want to get the ECU repaired so that it worked correctly, and have Robert diagnose what may be causing the failure.

    System32 EFII RPM & Dynon HDX

    So the OP was clear that he's using the FlyEFII ignition system, and (obviously) the Dynon SV EMS. The FlyEFII puts out ~12V pulses (when it's working correctly) and the Dynon EMS, in the "Tachometer" section of the EMS installation chapter (7, in revision AG) clearly indicates that there are...

    System32 EFII RPM & Dynon HDX

    I've had multiple hardware issues with FlyEFII equipment on various aircraft. If you have access to an oscilloscope, I'd put a scope on the output line (green wire) from the EFII box and see if there's a ~12v square wave on it at approximately 2 pulses/rev. (estimate engine speed by sound and...

    Intermittent "SV-AP-PANEL offline" message.

    Since Pin 9 is the input 12V power for the trim motors, it's difficult for me to understand how your trim system can work at all if the CB feeding pin 9 is disconnected - no power should be able to flow to your trim motors. It sound to me as though you've got some parallel path for power/ground...

    COM-425 Radio Exchange

    The installation manual clearly shows differences between the mounting of the C25 and X25 systems in chapters 16 and 17.

    SV Knob panel with HDX

    You've gotten a bunch of responses indicating great support for the knob panel. And if you have enough panel space for it and all the other stuff you want/need, I agree - it's very useful and helpful. But on my COZY MKIV panel, I would have had to lose either the COM head or the A/P controller...

    VPS and PPS in new RV-10 build

    I'm with Carl, particularly with respect to system failure mode issues. I've installed VPX's in customer's planes, and I've installed many non-VPX systems. For a day VFR plane, the VPX is nice and has some cool features (but it's a very expensive way to get those features). If you NEED the...
