I think the instructions tell you to dry fit ALL the parts before glue is applied. At least you were able to debond it. Oh well, It happens to the best of us. Read some of the bone head mistakes in the "Worst mistakes" thread in the CLUB HOUSE forum.
I put in a CAUTION about the last former in the rear fuselage. Mine was soft and cracked when I pulled the sidewalls together. When you pull them try not to flex the rear former. If your former is spongy or flexable try gluing a stiffener at the top and bottom just big enough to work but not so large as to cover the pushrod holes. you would be suprised how stiff a 1/8 th part gets with a single piece of 1/16 th laminated to it. 1/4 by 1/16th C/A'd at the top and bottom om the forward side should do it. The instructions call for a rubber band to hold the sidewalls together while the top plate dries. Take care when do this opperation as the tail plate is cut with the grain and it can split as well. Just don't force anything and you will be OK.
Good luck.
