Mark, as far as the tanks are concerned, I was thinking of making up a full span (inboard to outboard) welded "D" box tank and then making a welded wing tank that is also full span inboard to outboard with a width forward to back that will result in basically zero CG shift from full tanks to empty. I also liked the idea I saw on someone's video that they posted of a tank on the floor just ahead of the spar inside the cockpit but would prefer to keep the fuel outside if possible. The plane will be flown as a single seater 99% of the time so I would like to build into it the most potential range I can as such. At this stage the skins are my main focus. The tanks bridge will be crossed when I get to it. The skins will suit whatever tank configuration I decide to use. Thanks for the input, much appreciated.
