I'm using fuel dots which I mounted to the firewall using a piece of vinyl tube ala spad fuse. It's screwed to the wall and I opened up holes in the cowl to access them. It worked really well. You can see my tank install, I love it cause it makes access so simple.

Well as she stands; I'll tywrap the battery to the wing mount at the trailing edge for balance. The radio will mount to a piece of ply in front of the servo tray. Install the switch, run the engine for final check, install the cowl and set throws, head to the field. Can I make it today??? Who knows. I'll fly today but don't know if I'll get this thing ready or not. I'll post some final pics of mine if all goes well. Eric sent me some pics of his build and he did a great job. Hope mine flys as good as his looks. lol
