When I transfer it, I get the last little bit out by flying nose high/wing low, its all usable, but you still have fumes so what the hey. And the wing tanks are, well, right there in the wing roots, I think I have a much better chance of ripping a wing off then crumpling the fuselage to the extent the tank would rupture. I did make a point of not having any electrical up in the wing roots, unlike some designs.
Then there's belly tanks, while they seem to be fairly common for the Super Cub pilot with all the bells and whistles, they've always spooked me, (but I still want one) I've never ripped a wing off or crumpled a fuselage (well just a little) but I have had trauma to the belly area. An interesting place to put your fuel when going into bush areas with maybe unknown clearance problems /rock etc. To be realistic it's all bad, too bad we need to carry it at all!

I notice once the wing tanks lower enough I pump the 12 g. up into them ASAP, on the theory that it be "safer" in a crash...its hard to give up another 3+hrs duration at cruise speeds so thats why I do it solo, this article makes me feel better! kidding....
You'll never get all the gas out of there in flight, right? At least a little left over. So you crash and that tank ruptures and there's a spark. That would be a hell of a fireball. Maybe not enough to kill you but you'll get more than a tan.
