"Forest of Tabs" Ground Location...

Does anyone have photos or links to URLS that show some good places to mount the grounding block from B&C on the firewall?

Best photo I can find right now shows the "forest" on the right side of the aircraft. It's a little hard to see in my photo. It worked well for me. I used the RV-7 Van's firewall plans on my RV-6. The interior side has the same ground forest tabs as the firewall side. Probably overkill but the interior one is almost full. I ran separate grounds for everything. YMMV

Found a better photo

I could show you my photos (they are on mykitlog), but you really want to find another rv7 with similiar accessories that you are planning. What other things hanging on the firewall or in the vicinity will dictate the best location.

I put mine on the firewall right behind the radio stack. My rationale was for access as the radio stack is the only major cutout I have in my subpanel -- that's the theory anyway.

Almost through wiring and this has worked fine for me.

Here's where mine ended up..

This location worked well for me, but just ensure you have clearance for removing the battery.

Just to the right of the radio stack cutout in the sub panel.

I put mine on the interior of the firewall, up high and near the center (over the battery).

You can see what is on the other side (engine side of firewall). Plenty of room for the cowling hinge pins. Engine ground strap comes to the stud on the far right. Battery ground goes to the larger stud on the forest of tabs ground block.

There are likely a lot of good spots to mount the FOG, and its not an expensive item, so why not mount one. I asked this question early on, but waited until my electrical, instrumentation, and engine monitoring firmed up. During designing my system and choosing the components, I kept an eye on the Fwf grounding requirements. Well, my dual Dynon Skyview with Ems is fully installed and operating, ie, all electrical is complete. Not a single Fwf ground other than the common point on the firewall for the battery and engine ground anchored with a bolt. My assumption is that a lot of the need for Fwf grounding may be pre-glass panel/ EMS. I do have a large FOG behind the panel with probably a dozen tabs used, but none Fwd.

I put mine above the battery on the upper portion of the firewall. I do not have any tabs on the forward portion of the firewall, couldn't see any use for them. Although not showing in the picture, I have quite a bit of my electrical run now and it is working out well so far.
