Ahn, or anyone else with an Accuracy Avionics Panel for their  10:   Where are you placing the primary and secondary power  grids?  Looks to me like the forward surface of the subpanel would be  okay;  a little hard to reach but doable.  Also could the manifold  pressure sensing unit go there as well?  I also plan to put the door  closure indicator relay units there too.  All suggestions  welcomed.  Jay Rowe

Jay,    We are using  the Acuracy Avoinics  glass instrument panel and center console in our 10 and we are working out the  details now.   We have the version of the panel with the centered  radio stack.   We are using AFS 3500s on each side and a center stack  of a GMX-200 mfd and 2 garmin 430w.   I think the real challenge is  the cutting and re-supporting of the three main instrument panel  ribs.    I'm just days away from posting the pictures of how we  did it.    When we are ready I'll add the pictures to the RV-10  section of our web site.    We machined an aluminum arch out of  billet 6061 aluminum with an L shaped profile to resupport the material that  just has to be removed from the three ribs to accomidated the AFS  glass panels.    I think most of the power and ground buses will  be attached to the forward sub panel.   Additionally,  I'm  putting a small fuse block bus in the rear of the aircraft on my equipment rack  I made behind the baggage area.  I have pictures of that already up on our  site.    more to follow.

This may be hard to explain and I got my panel from Stein.  But here you go.  I have three power buses, main, battery and e-bus.   I took a little different route.  I used a flat piece of AL about 4” by 6” and mounted my MP sensor, trim relays, a terminal board and a couple of other things.  I used both sides.  The I mounted that on the bottom of the subpanel, the flange, using the three bus terminals to hold it in place.  So, if I need to work on anything on that piece, I just remove the three bus connections and the panel drops down.  

   

Because of a MP problem……I pushed the pin the wrong position in the connector…..I have had to drop it once already and it worked pretty good.  

   

Sorry, no pictures…

Jay, 

I mounted the buss on the left forward rib. This left a short run from the buss to the starter relay and my main feed runs down the left side also. I mounte the rack using nutplases so if I have to remove it I can do do from underneath the panel...not fun but doable. I mounted the manifold pressure transducer on the right forward bulkhead facing the fiewall. Makes for a short run to the bulkhead adapter. I know you goiung to ask for pics but.....I have to find out where in my vast photos files they are. I have all kinds of pictures of that area but none of exactly what your looking for.

Oh yeah,...mount the door relays to a piece of aluminum matched drilled and install nutplates to anywhere on the ribs or bulkheads. Attach the relays to that little aluminum piece. Hook up the relay leads to the relays and intall it a one unit where you made your nutplates to hold it. It is way easier to slide the terminals on then mount the relays....trust me, I just hooked those up an hour ago.

[quote]   Thanks Bob, Rick, and Rene.  Great suggestions that I    will (did) incorporate.  Actually what I did today was fashion several    alum. angle strips to run on the bottom of the three forward ribs then    attached those to the ribs with large nutplates.  Then riveted the power    grids to the angled alum. with the grids facing downward.  The result is    they sit low enough in that forward subpanel space that they are easy to get    to for attaching wires and such.  And, if they have to be removed to    replace fuses (or any other reason) they drop right down by removing the four    large nutplate bolts.  I also beefed up the ribs just a bit    with several small pieces of angle stock.  I also have enough room to    mount the MAP box, the door indicator relays, and probably the Lightspeed box    if I decide to keep it out of the engine compartment.  And, by the way    Bob, with my set up (two horizontal GRT screens and the cantened center radio    stack I did not have to alter the anterior ribs at all). I did provide some    additional support to the radio stack by running some angled stock from the    stack up to the already reinforced center rib.  Jay
