RE: Building a Dynaflite Super Decathlon
Here is what the plane looks like with the #4 and I'm guessing #3, bulkhead looks like installed. It's important that when laying down the fuse bottom that the top of the fuse bottom cut outs match with the plan for proper firewall attachment. Don't do like I did and glue bulkhead #4 on the the fuse bottom on upside down. It's not a good way to start your building day.
When I was clamping the firewall to the fuse, I didn't have a clamp large enough to get across the lenght of the firewall so I had to come up with this ingeneous method.
