Goldwing - See tech notices listed with the Pitts specs at G.P. for additional info on this........ I used 1/8" wooden dowels at 1" in length. I used 3 on each side and pinned all four sides. Just like I'm sure you are familiar with. As for fiberglassing, I simply used fiberglass cloth and then 'Finish Epoxy' for resin. I covered all corner areas all around the mounting box as it mounts to the firewall. I had thought RORO had posted pictures of how he pinned and fiberglassed his model. I couldn't locate on this thread. I will post a picture tonight when I get home of how I just finished pinning and and fiberglassing mine.

RCISMYLIFE - Thanks for the NiMh info. Thats what I was hoping. Sounds like you have high confidence without any negative consequences. Wish others would pipe in on this.
