    Bunch of Good Stuff came in last week ! Radios and such. Changed my mind on instruments too. Ordered a GRT Sport 10.1 EFIS with their engine monitor, that'll be here in a few weeks. Then I can start wiring up the panel (-:

      I really like the GRT stuff I have, and being a native Michigander feel good about sending them my money. If you mean the engine monitor I think you do, the concept is brilliantly simple. Once setup (and that's so easy to do, you can actually change the parameters in flight) a panel mounted light glows steady if all is AOK. If it starts flashing, you have reached the upper limit of a particular function. This frees you from continually scanning multiple readouts, it's an idiot light in effect, but a good one, freeing up your attention for flying the darn plane. I have had mine flash one time, and it worked. I blew a seam in my radiator (Rotax, 2600 hours, a seam got "work hardened" due to expansion and contraction, it was a Chinese core, not now) on climbout in 8 degree temps, the flashing light got my attention instantly, and I landed without further damage.

        I opted for the Sport 10.1 EFIS and have the engine info on that screen to declutter the panel. And yes they have great features on the engine monitor, plus a reasonable price for the equipment.

          I'm preparing to upgrade my panel on my RANS S-6ES to add a GRT EFIS as well. But I don't have room for the 10" version, so I've been going back and forth about whether I wanted to go with the Sport EX (7" display) or the Mini-AP (4" display – just barely larger than a 3 1/2" instrument it would replace). After doing some in-depth wiring planning (assigning serial port connections to all the various functions), it turns out that I would save less than $200 by going with the Mini, versus the Sport EX. So now that decision has been made. I will integrate my current GRT engine monitor (1-wire connection) to the Sport EX, and have graphical display of all the engine-related stuff as well.
          To make panel access easier, I'm going to cut an oversized rectangular section out of the existing panel, and use a sub-panel that will contain the GRT and a couple of other instruments (Belinte Radiant Instruments "Angle-of-Attack" and "Digital Altimeter"), plus the "Low Fuel" and "EIS" warning lights. I'll post a "mockup" picture if/when I ever get my Internet connection up and running again.

            I replaced my steam gauge ASI, VSI, Altimeter and compass (a compass isn't needed if you don't night fly I believe, after realizing I had NEVER looked at the compass in the last 25 years in several planes, since GPS came out, I yanked mine) and replaced them all with a GRT Mini. It works great, saved a LOT of weight and to my surprise there was no period of getting used to it, it felt "right" first flight. Plus, I can now fly blind, using the artificial horizon and turn indicator. Just kidding, but it's fun to play around with it sometimes, in VFR conditions.

              In the US, 14CFR 91.205 (b)(3) requires a magnetic direction indicator (some folks mistakenly think this means a compass) for all VFR flight, day and night. This makes sense, because a GPS can only derive your track across the ground. A fancy GPS can take your magnetically-derived heading and compute winds and drift. In our plane, I don't have a panel-mounted compass, but instead use a magnetic sensor that displays its results on the instrument screens.

            Yeah, I'll have a magnetometer installed in the wingtip.
