Nice repair job and thanks for sharing your story! I would suggest reinforcing the firewall as another gent mentioned. I can't believe CG didn't even put some tri stock behind it to give it some support. I usually drill and pin the firewall from the sides and bottom as well. That's my only gripe with ARF's, poor glue joints and weak construction on lots of the planes. I usually spend about 2 hours reinforcing them before I ever fly them. DG
