RE: Question about my first kit build
You got two choices.
1) Fill the gap in with strips of scrap balsa and CA or wood glue
2) Fill the gap in with wood filler and coat it with CA if necessary after the filler is dry.
In either instance you should fill the gap inside the fuselage, as well as all the other joints, with wood glue such as Titebond II.
And no matter what way you choose to fill the gap, when it is completely dry sand it smooth and flush with the fuselage sides.
The gap does not seem to be that significant enough to have to rebuild a new fuselage, just fill it in and sand smooth. I have had similiar gaps in some of my builds and was a very easy fix. Everything still remained square at the end.

Built one and used titebound wood glue, forget the CA, fill the gap with titebound and sand it, be careful with the balancing, it can get tail heavy and be a real monster, used a 46 on mine it was a great trainer, later rebuilt the wing and it was a good sport trainer

RE: Question about my first kit build
I agree with the titebond II to fill the gaps, that WOULD BE easier to sand than CA. So use the titebond II to fill the gaps, but you will still need to shove some balsa scraps in those gaps to help fill it in, then sand it all smooth. IMO there won't be any balancing issues as MOST of the gaps are running the length of the fuselage and not the rear-end.

RE: Question about my first kit build
In future builds do some test fitting and work to get the parts to fit properly. A joint gap filled with glue, scraps or CA just isn't as strong as wood touching wood with the proper amount of glue. These "gaps" simply should not exist.

Get a piece of scrap balsa and sand it to make a small pile of sawdust. Mix the sawdust with wood glue to make a paste.
Fill the gap with the paste, smooth it out, let dry and sand.
