Hey, WHile a new start is great I find it alot of fun to reapair older or crashed stuff.. Plus that $100 or so could go towards a second plane... Pick up some Thin, Thick, and Medium CA fromyour LHS along with 5 Minute Epoxy... Repairing the tail shouldnt be all that hard.. Look at the other side of the stab and at the pieces needed to build it.. Then purchase the balsa fro your LHS and build away.. SHouldn't take more than an hour or two.. As for the crack in the fuse can you get a picture? If its a hairline type crack you might just put some thick or medium CA in there with a popsicle stick on the underside.. Where is the fuel soaking? Thats what Has me worried. Can you getsome more detailed picts?
