Tim, Good to hear you're finally getting into it! Sounds like I'm about 2 weeks ahead of you. I have my fuselage sides laid out, gussetts cut, etc. and this weekend I plan to glue it all together. I've gone for the extra 14" bay behind the spar and added an inch to each bay in front of the main spar (3" total over the 2S). I think this is pretty much what Mark L suggests he would do if he was to build another one. I'm planning to make mine 43" wide and to make the widest point at the shoulders of the occupants (can't remember how far that is behind the standard position for the widest point). I'm planning to build to the standard firewall dimensions so I can retain the option of using any off the shelf components (e.g. cowl, engine mount, etc.) firewall forward. I'm hoping the extra length will offset the extra width and reduce the tendency for cracking when bending the sides in which a lot of people seem to experience with the longerons. I'm using hoop pine (an Australian species) which is about 10% heavier and 15% stronger than spruce. I haven't yet found any info on how it compares for resistance to cracking when bent, but I expect I'll know soon :-)
Good luck with your build.
