A good start
The cutting process went very fast, most of the parts were cut as an apple pie was warming in the kitchen (Mother's Day desert). From the layout of the parts you may get an idea of what the fuse will weigh after it's assembled.
Time to glue
My second favorite part in making a model is the step when things start coming together. My glue of choice is low temp hot glue because I'm impatient. I'm sure there are lighter more durable glues out there, but for me, hot glue works the best. There are other down sides to hot glue as well, for instance it does not sand well at all. But the flex it has when it dries and the ease of construction more then make up for negatives.
Hot Easy Glue
Since when released the FFF does not hold the shape it was bent into having a glue that cures quickly is important, unless you want to build elaborate rigging.
To fit this piece together, I glue the seams and grab it the same way as it was grabbed on the last page. Hold for ~30 seconds and it's ready to go.
Folding the DOW FFF is very easy and does not require any heat. You just slowly bend towards the printed side, away from the covered side, and glue when your ready.
The exact shape I need is not there yet, however I have a good seam where the foam is joined. The nest step is to drop in the former, the profile part.
Once the shape is glued in, it may be a good idea to cut out an opening so that wires may be run through the profile later on.
The entire fuselage is assembled in that very same manner. One section at a time, joining two together when ready. It's important to dry fit parts just incase something went wrong, but worst case is frustration as really anything is easy to fix. I should say I found two problems with the plans, both very minor. The first is the profiles were mislabeled in one instance. Number 3 should be 4. The second is that the oil cooler part will need to be cut before it's flipped to obtain a foldable flat pattern.
What impresses me the most is when this is put on the scale. Almost unbelievable results.
Yes, that indeed says 2.1 ounces. The weight will of course go up, there is painting, hardware, and other "parts" to be added before this is finished, but this is a very good start.
