Since I am in Atl, Georgia right now I decided to take advantage of the 2-4 day shipping. I ordered the skirt and some plastic parts: acetal pivot rods, acrylic hinges and some acrylic screws.

White Acetron:
- Acetron GP is a general purpose acetal and is the only porosity-free acetal product available today. Service temperature, air -50 to 180 F. Not UV stabilized. White meets FDA standards and is USDA compliant. Ultimate tensile strength, 9500 psi.

I could have printed my own hinges, but this is way cheaper and faster.

I aslo decided how I'll contain the lipos. The battery bay will have very thin metal (most likely aluminum) sheets around the bottoms and sides. The top will be a clear hatch, hence the hinges.

Might anyone know where to get m2 nylon (or any other type of plastic) nuts and bolts. I've searched my head off, without any real results.

I just ordered some nylon nuts, bolts, and washers. I may need more later, but at the moment, I can't fathom any other need.

The bolts above have a female thread. I thought they were pretty cool, plus they don't weigh anything compared to metal. I have no use for them, but I might find something.

This is by far the most expensive prank I have done!

I have the skirt, pivot rods, and some of the lesser electronics are on their way. I will be back home tomorrow night so I guess I'll get the foam on Monday after school.

I have been back home from the 9th. After bad weather (blizzards and ice) in Atlanta, I finally got my skirt. Well I already had it, but I had it up there and now I have it down here where it will be used.

I'll hopefully go to Home Depot today or the foam.

Operation X-Craft is now in effect.

I have the base foam, skirt material, and have some electronics and miscellaneous gear on the way. I will start marking the sections to be cut on the foam tomorrow. I'm still looking for a 28"-32" drum to form the duct around. I also start posting pictures and procedures in the construction post.

Still watching with interest.

I am contemplating on what type of glue I should use... Gorilla, Foam Tac (Beacon), epoxy, or other.

+ cheap
- I have no experience with it, therefore unpredictable

Foam Tac
+ the best glue I know for any types of foam
- more expensive in the required quantity

+ has proven itself in all environments
- heavier

How are you cutting the foam?

I cut the parts with a table saw in a friend's wood working shop.

This is the total area of the gluing surface. This is where weight becomes a concern. Would you still say to go with the epoxy?

That is a total surface area of 528 sq. inches.

I would not use epoxy. It is heavy, so if weight is a concern... Also, I personally don't think epoxy works very well with foam. I've never had good experience with it. I say get the Foam-Tac. You get what you pay for, and this is a project worth buying quality stuff for.
