I built a scale model of the A.S.P. for NARAM 49 so it wasn't exactly like the Estes kit but you might be able to use these ideas.
I used 1/16" balsa. Attaching the fin tabs is a pain and they usually get taken off in the first flight. The scale data shows the tabs on a side of the fin and not centered on the bottom. So, I made card stock overlays of the fin and tab to go on one side of the fin and just a fin for the other side. If you plan on attaching flares to the fin tips, the overlay helps to keep them secure (I had one break off on landing but it was an altitude event and I used a streamer instead of going with a small parachute).
I used ST-7 tubing and nose cone from Semroc. I cut the tip of the nose cone off to install the antennae and then used squadron putty to re-build and shape the nose cone around it. You can use the extra weight because it's initially a little unstable on a C motor but straightens out and flys straight. Fin tabs create quite a bit of spin..... 
Anyway, here's a picture of it........
