first I remove the fin and tailplane then I cut the fus top and bottom along the join with a long blade, you then see where everything goes and repair damage internally, then I join the broken side when dry (with all rods etc. in place) I join the 2 sides with UHO por and some thin ply on the outside. make sure it is straight/inline before adding the ply (I didn't and had to redo!!!!) if looks bent then steam it and it will straighten. don't look new but flies OK.
