    I think I've been heeding everyone's advice as best as possible, and this is what I've come up with.

    - iPad removed: there was definitely alot of screen up there, but I do like having a second so I kept the 7" HDX since it'll sync with everything else

    - I like the extra modules that Dynon offers. Touch screen is unbeatable, but sometimes is nice not to have to access menus for everything. Some people like a clean panel, so I totally understand why people might disagree with this choice.

    - EP912Sti has 2 ecu lanes, and 2 fuel pumps seems like an obvious choice, so that's why those each have 2 switches. The EP912STi comes with an 18A alternator, with a 32A bolt-on option. I've put 2 switches there to easily isolate them for checks during run up, or in operation, and they can be "stacked" if I want to run an AC inverter or some other high draw item (who knows!?)

    - I'm with most people here in that a clean stick grip aside from PTT seems like the way to go, and trim next to the throttle seems like it might be handy. I've put a little lip on top to serve as a hand rest/guard for the trim. Thoughts?

    - Starter is a momentary ON-OFF-ON, Master is a locking ON-OFF. As per Eric's advice, a radio and avionics master do seem like an unnecessary feature/single point of failure, so they've been removed. Yes, the buttons are still illuminated, but they'll be wired to have an independent power source which will be dimmable....if I cant make this happen, they will not be illuminated.

    - Passenger reading light seemed like a nice idea since I took away their iPad

    - Still undecided between Vertical Power VPX, and standard breakers/mini fuses

    - You guys were right, this thing is definitely never going to be an IFR flyer, but I'm still hanging onto that pitot heat unless for now. Maybe someone can give me a nice alternative to take its place on the panel?

    hmmm very interesting! Do you know if the intercom module is required? It would be weird if the HDX couldnt handle basic intercom functionality itself

    There's no intercom functionality in the EFIS. It must be added separately.

    What are the functions of the two ON positions of this switch?

    How is ignition different from the ECU Lanes on this engine? Is the ignition system pilot-controlled separately from the Lanes?

    Passenger reading light...
    Located where shown, it will be pointed at the passenger's knees. You might consider mounting it to a small bracket in the overhead structure, and put it in the middle so either occupant can use it.

    How much flying will be done at night with passengers who want to finish their book enroute?

    Start and start, so it works in either direction...for fun

    I thought the ecu lanes each controlled the ignitions?

    I guess it's pretty obvious I'm just looking to spend money on useless **** eh?

    I would give more thought to mounting the trim switch next to the throttle. You have to deliberately hold your arm up, supported only by your thumb. Down on the center console in the standard location is so natural because that's where your arm naturally goes when at rest; its so easy to just extend your finger and operate the trim. I find most trim adjustments are made without changing throttle settings, so your hand is not near the throttle. IMHO

    I'm with Jim on this as well , the trim on the console is in a great location where your hand goes naturally, and you usually just need to "bump" the toggle for the right amount. Trying to do this by holding your arm out to the throttle area would be more cumbersome. Bruce N199CL

    We’re still building so I can’t speak to how some of our options will be to fly with, so take what I say with a grain of salt!

    Our trim is on a bike grip with a four-way toggle/ptt button. Tracstarr used this set up on his build and was happy with it.

    Take a hard look at the Advanced Flight Systems ACM. It integrates seamlessly with the Dynon avionics and you can also order pre-built wiring harnesses for 90 percent of what you’ll need. Saves a ton of time and so far AFS has been great to deal with.

    Like Shadowrider, I wanted everything off during engine start except the HDX, so an avionics master was used.

    Is it the Otto T5 tracstarr and yourself are using?

    I think trim button on the center console at stock location is the best because you’re close to the flap lever. Drop the flaps and hit the trim, or pulling flaps and adjust trim. Pretty seemless motion with right hand as your flying and radioing using your ptt on your stick with left hand. Allows for all to happen at same time. I often find I am talking on the radio, dropping flaps and then trimming, plus power adjustments all seem to be seemless with right hand.
