Cracked Root Edge Joints? TIP
On the left is my well worn Quest Striker AGM with 13 flights on it. The low half of the fins continually crack away from the plastic tail cone. The instructions said to use CA to attach them but super glues get brittle over time. These root edges were cracked after the first flight.
Here's the newer Estes Honest John after the first flight. All four fins have cracks at the root edges. The entire root is set against the plastic blow molded tail cone. The fins are through the wall with fin tabs glued to the motor mount tube.
I'm curious if anybody else has had these cracks where the fins are glued to plastic. Leave a comment if you've noticed these breaks at the root edge on your models.
