I did lots of testing, and finally found what I think is the strongest weld I can get. I start off by using Plastruct plastic weld (glass bottle, orange label, bought it at the LHS, this stuff
http://www.kitkraft.biz/product.php?productid=1418) to set the basic joint. Let that dry for a minute or two, so the pieces are connected how I want. Then I "paint" the abs on around that in thin layers.
This is fairly strong on its own, but will break if you use enough force. That's OK! It breaks because the ABS gets little air bubbles in it. If you use the plastic weld to fix those breaks, it fills in the air bubbles, re-welds the abs, and becomes nearly unbreakable. It's kind of crazy how well it works.
So yeah, I fully expect some major breakage on my first big crash, but I know ahead of time that the fix will actually make it stronger. Took a lot of trial and error, but I'm really amazed with the welds I get. Was very worth it.
