If you plan to be in this hobby very long, you have to learn to make repairs. Especially when you are just starting out.

The repair photos earlier in this thread showed how to make a splint with carbon fiber rod and fasten it to the boom with dental floss and CA glue. Too bad that's gone, but here's a photo of one that a guy reinforced with some wood and zip ties, just use CF rod instead of the wood, and dental floss & CA instead of the zip ties.
