Hello, I wonder if any of you can help me.

I'm a make up artist currently working on a film in which one of the actors noses has to be turned into a plane nose with moving propellars. So we were thinking about using a battery propellar small enough and light enough to fit into an actors false nose!

Have no idea what to start looking at - haven't the first clue when it comes to propellars or planes! We are looking to carry out a test make up first so nothing too expensive! Have any of you got any recommendations?

Where do I go? (Where are the best aircraft model shops in London?)
Or are there any good websites?
What size/kind or name of propellars should I be looking for? And battery?

ARGHHHHH! As you can see your help would be greatly appreciated.

Thank you

Ella.
