Top turtle deck.
Install the top sheeted core - remember I sheeted these babies like 3 months ago
Carefully finish sand the edges of the core and position it per the plans, I use a very thin coat of gorilla glue or 30 min epoxy to attach the turtle deck. Do not install the lower fuse core till after you do your wing and stab alignments.
The turtle deck needs to sit inside the fuse sides by about 1/32" - to be sanded with a slight curve when finished.
