There are one or two apps/websites out there that can magically transform a load (about 50-80 seems to be the norm) of photos you take of an object, and create a 3D model from it, such as:

I’ve never tried it out, but it’s the kind of magic normally reserved for people in movies saying “enhance” to their computers when faced with a low res, blurry image.
The process seems to involve just moving around the object, snapping photos, then uploading them to the website, and voila! It creates a 3D object! How you actually convert the .stl file to something After Effects or a 3D program can work with is another matter which I haven’t looked into. You can also order 3D “prints” of the models, so if you want another toy helicopter (probably costing far more than the original toy!) then you can get one made from your photos.
To have the helicopter fly around in 3D, you’d have to render it in a 3D program (anything from Maya or Cinema 4D if you’ve got a few thousand £ or $ to spend, to Google SketchUp which is free) then comp the rendered images onto a background in After Effects.
