RV-10 Install
So what are your thoughts about an RV-10 install considering the battery is in the back...sounds like you will still need a contactor in the back with the battery...

Technology
There are people who swear by new technology and some who swear at it.
I am of the belief that simpler is better (KISS). Take our latest generation of cars. Lots of electronics and only the dealerships have the secret sauce to fix them.
What I like about my plane is that I can actually work on it and debug most of the systems. Sure some of the electronics (I have Dynon and Garmin) may have to be returned if not working but the fundamentals that keep the plane flying are extremely simple. So if my Dynon and Garmin stop working in flight, I can keep flying. When on the ground I can debug just about any engine/ignition problem. If there is a problem the ignition parts, they are inexpensive and readily available.
Technology improvements are great but they have to bring greater functionality, reliability or value. If they don?t, I don?t believe they are worth the time or money.

Good product
Keep in mind this will not be released until it has sufficient time in service with test units. Things are always evolving. Some embrace it some don't.
The PPS will save some install time, although to most it is not a big factor. I know people have mentioned the issue "what if it fails?" We can apply that logic to anything. In reality how many failures have occurred with a master relay and start relay? Not many.
Everybody was concerned about the VPX being the internet popular, "single point of failure." That has not materialized. Conventional breakers are old school but still valid. Too me a panel looks a little strange with all the modern glass then a panel full of old school breakers.
I will say the price of the PPS might be a limiter for many. I was hoping in the $500-$600 range. Especially since doing it with a start relay and master relay will only be about $100.
Lets see how it plays out. I commend them for modernizing and coming up with new solutions.

I had a battery contactor/solenoid fail on me last year on an IFR flight. I lost all electrical power. Fortunately I was VMC and dropped into a nearby airport with a mechanic on duty. He cannibalized a contactor out of a 182 and I was on my way. These are mechanical parts, they fail. It seems solid state would be an improvement in safety/reliability. No?

Yeap, it sort of remind me of a friend that spends another extra $1000 on his bicycle that is a few grams lighter. I asked him, isn?t cheaper to lose that extra 18 grams then spend so much money on a set of rims to save a few grams. But then again, some people won't mind spending thousands to save a few and since it is their $$$, more power to them.

While this would be out of my price range, there are certainly plenty of people to whom money is really no object (that seems to apply to many RV builders), and will gladly pay to have the latest and greatest. I don't begrudge them that, and in fact I thank them, because the early adopters are what help the new products get developed, and eventually, be priced within reach for all of us. Most likely, when it's time to replace my relays and solenoids, something like this will be a viable and cost effective solution.
Most new technology isn't cost-effective at first. It's the early adopters who help make it so.
Thanks to all the vendors out there willing to take the risks to bring these things to market.
Chris

Hey Chad
You have not talked about additional features. Back in the early '70's VW had this magic "diagnostic" plug that could do engine analysis at service intervals. Mostly it was premature and a failure, but it did have a couple of cool features that worked very well.
The first is compression test. When the engine was spun with the starter, it would measure the amp draw accurately enough that it would give a relative compression reading for each cylinder. The second was a battery discharge test. It would apply a small known resistive load and then record voltage drop and give an assessment in % of battery capacity. Both of these (and more) could be easily integrated into the new module. So - what new cool features can this thing do that, beyond just a replacement for the contractors, would add to a pilots confidence in the health of the airplane?

Mark, CPC connectors are extremely easy to wire. All you need is the terminal crimping tool which you can find pretty inexpensively on eBay. I'm sure they will be providing a mating harness with wires so you won't even have to crimp the terminals.

Can someone please explain why it would be a good idea to hook two alternator B-leads to the same terminal?
Or, did someone just mis-label the mockup?
