Consider Subscribing and Fly Along! How much did Dynon SkyView HDX cost me and my whole panel with Avidyne IFD540. If you already have a good GPS you do not need to do what I did and get all new stuff. It will save you a lot of money just getting the Dynon SkyView single Screen. Thanks for Flying Along!

Another good video!  Go Dynon!

About the backup batteries and length of time those batteries are good for, maybe you have touched on this and I have overlooked it, but many people don't really understand what those batteries actually do or don't do. The back up batteries will run the displays, ADAHRS, engine monitor and Dynon GPS. The back up batteries will not power the autopilot servos, com radio, transponder, other GPS navigator, or anything else in the airplane.  Those loads must be entirely carried by the aircraft main battery.

Several years ago, I was on the way in my Dynon equipped RV7  from Charlotte to Pittsburgh and had an alternator failure.  Good weather just behind me, all the way back to Charlotte, but low IFR weather at and within 50 miles of AGC/Pittsburgh. I called ATC and advised I just had an alternator failure and would like to turn South, direct 8A6, my home base.  They answered, right turn 180 degrees, when able direct 8A6, would you like higher or lower? Huntington weather is good if you want to go there (hint, hint). No thanks, headed home.  Shooting an ILS on battery power alone and being stuck in Pittsburgh with a dead alternator, neither was comforting.

Turned the nav and strobe lights off as it was just after sunrise, and turned one display off. According to my Dynon display, the amp draw was about 6 amps for the one display, GPS, nav/com, transponder and audio panel.  Two hours later I was on the ground at 8A6.  Bus voltage had dropped to 11.4, not low enough for the display backup battery to kick in. The transponder and nav/com were still working.  I could have gone on for another 30-45 minutes on the aircraft main battery.  New avionics really don't use much power and seeing accurately what is going on as far as load and voltage allows a lot of decision options.

The Dynon batteries will power the displays for an hour, the D10A for a couple hours.  Will you aircraft main battery power everything you want and need for that time?  What load can you shed?  How? What will it do?  If your displays are on a pullable circuit breaker, they can be removed from the bus and powered by their batteries to reduce the load on the aircraft main battery.

A what if/safety video?

According to my Dynon display, with a fully charged battery, my entire airplane is pulling 2 amps or less. 
 

also, if you have the ability to go this route I did my install on my own in the Florida heat in about 3-4 weeks. At a cost of about 27k.

Thanks, good video.  I knew very little about the Dynon system but I was a little surprised by a few things. 
 

First, while it looks like a great system, the pricing starts to look pretty similar to the Garmin equipment (maybe I missing something).  The G3X dual 10 inch setup is around $16-17k in the Garmin unit and looks like it would be $15k for Dynon?  I’m not saying that Garmin is necessarily better, but it seemed like Dynons mission for years was to create more cost effective avionics (which I assumed was more than 10% cheaper).  Second, some of their pricing seems to be very “spirit airlines” like.  So you need a USB port to update the unit but it’s an additional add on?  Why not just include it in the price?  Oil temperature is an additional add on to the engine monitor?  I can’t imagine anyone wouldn’t want to know their oil temperature.  None of these things were expensive, but why not include them to seem less like they are nickel and diming people?

I’ve heard that the real savings in the Dynon over the Garmin G3X are in labor. There isn’t as much labor in wiring since you are buying Dynon harnesses

May be true, but based on the video at $16K, the labor seems to actually be more than what I've been quoted for comparable Garmin system.

@Davidv The 16k is not just for the Dynon.  The 16k was for the whole panel project.  If I was just going to put in the Dynons and had everything else labor would be approx 7-8k.

Yes I’m talking about the same, but I’m not trying to split hairs or say you didn’t get a fair deal at all.  Every installation has it own complications.  My comment is as more about expecting the Dynon to be significantly less but I guess they found out that it costs a lot money to develop quality avionics

Your right.  I could have toned it down and got 1 screen and not 2 but what the heck.  lol But I figured while everything is apart lets just get it done.

I’m doing the same with mine, I’ve got a bad case of the “while we’re at it”s!

LOL.  Its a true story.  Another reason why I said replace all the old wiring.

When it comes to the harness, I got the dynon harnesses and I'd say to get it all spliced together (I soldered and heat shrank) probably took about 6 hours total not counting the engine probes.

that labor cost seems very reasonable. The panel is considerably more work than I expected. Also making it all fit, especially the right side, is not easy. 

I have all the cad now, but getting to that point was a challenge I don't want to do again.
