If the edges don't sand easily and fold over, chances are they aren't glued down. Slip a little white glue underneath the raised paper and spread with a blade.
When the model is finished you'll want all four fins to sit flat on the table.
To check the bottom edge I used a CD case, it's square and handy.
Here the root edge is facing up flush with the CD case side. The trailing tip is to the right against a sanding block.
Enlarge the picture and you can see one side of the trailing edge is higher than the other side.
Sand down the high side until all is square against the sanding block.
After the trailing tip was sanded square, the exposed balsa edges were filled with CWF.Brush just the open balsa grain.
If any CWF gets on the flat sides, wipe it off before it dries. (See inset)
Don't sand the paper covered surfaces. That'll just "fuzz" up the paper and make for more sanding after priming.
