Starlight Jayhawk Build Part 6 Fin Fitting


After setting the root edge of the fin on the body tube and shroud, a tick mark was made at the start of the shroud taper.

One side of some scrap balsa was sanded square and then glued to the fin's root edge with super glue. Note the front edge is right at the tick mark.



The fin is set against the body tube and a reference line is drawn to fit the shroud. Start sanding with a block, constantly checking the fit of the added balsa piece.





Now I'm getting close. You should only be sanding down the added piece from the tail cone down.

When you get to this point, switch over to a finer grit of sandpaper and check the fit more often.




This is about as close as I'm going to get.

You could keep sanding, but run the risk of taking off too much of the root edge making the fin smaller. Just get it as close as you can.
