I'll let the annotated pictures explain it. It was a fun build.

I recently found myself donning my mini-tricopter case with decals of the companies that supplied the parts for it; I don't mind advertising for small companies that need it.

This method works for case decals, planes, cars, helis... pretty much anything that 3M 77 will stick to. Which is just about everything.

First step is to find your graphic. In this case it is a Flyduino decal for the Nanowii board inside the multicopter inside the aforementioned case. Once you've found your graphic, print it out with the desired size.

Next, cover the graphic with packing tape and massage it in with a flat object, I used a moulded plastic case from a voltage monitor. Work it in with enough pressure that you get 100% bonding from the tape to the paper. It takes a bit of effort but you'll see what I mean when you finish.

I've been a big fan and loyal customer of Altitude Hobbies, a small hobby shop in Colorado with top-notch customer support, nearly instant shipping, and a great product selection. The owner, Garret H, is a chronic RCgrouper, too, and is in my friends list.

I recently bought a slow stick, and realized that it was "altitude blue", and then realized after I built it that I had used 100% altitude electronics on it. So I slapped on some homemade decals (printed on standard paper, cut out, then 3M-77) and am dubbing it the unofficial official Altitude Hobbies Slow Stick.

Tail Decal. This picture doesn't really do it justice as the stick's tail is alot darker blue. The contrast is more like the next picture.

I dug out an old motor from the toolbox when cleaning it, and I didn't even know I had it. So I built a plane to stick it on.

Here's the stats from a CG calculator, showing what I did with it:

The construction is fairly simple... a main wing shape and then a kFm2 step on top. LE is duct-tape backed with gorilla glue, which makes it a hard plastic leading edge. Some winglets foam-tac'd on with some scrap EPP. After building it, I realized I didn't have enough area to make suitable surfaces, so I stuck 'em in the back. The airflow over the wing will be pretty turbulent but I think it'll work.

I've been disappointed that my summer schedule has been quite full... full enough that I really don't have much fly time, or being in one place long enough to completely follow through with a scratchbuild. I'm flying to hawaii for a robotics convention (I'd rather it be in CONUS - I'm gonna be too busy to enjoy the island and staying there is expensive). Then a week on an island in virginia, among other things.

So, why not bring a plane with me? I'm pretty much a warmliner/hotliner pilot, so a 700mm-ish warmliner shouldn't be hard to do. I couldn't sleep after I thought of that idea. Here's what I've come up with so far:

This thing has to be durable. Not as durable as a combat wing, but definitely should be able to resist tears and nicks and moderate bumps. My go-to higher-quality foam design is an EPS-cored fiberglass v-tail. It's just a bit too brittle and finicky for a rough-handled traveler.

I was just browsing rcfoam, looking for inspiration, when I found it. In the form of Carbon Fiber Tissue. This stuff is somewhere between wove carbon fiber and 1/2oz fiberglass cloth. I could coat it with this neat RCfoam stuff called 'Extreme Coat'. It seems to be a liquid rubber coating that leaves a flexible end result. I thought about laying in carbon fiber tissue between a few layers of that stuff on top of some reinforced EPP cores. End result would bounce in a crash, yet be resistant to tearing and bumps better than plain 'ol EPP. I like it.
