This instructable is for how to add an extra dimension to your model aircraft; a working propeller (and lights!) which is surprisingly good as a desk fan. It can be adapted to any aircraft of most scales, although you would struggle to fit it into anything smaller then 1:72 scale. You could also use the same principles to make one of those plane-on-a-string things that fly round in circles, or even make an r/c version! I am assuming you know model-making basics such as glueing, painting and adding transfers (if you want advice on these, there are loads of good websites and other instructables on this). 

You will need:
A Model Kit (mine was an Airfix 1:72 scale Spitfire mk1a)
A micro-motor (I got mine from an old r/c boat; also available from the internet, including here: http://www.wheelspinmodels.co.uk/i/93255/)
Wire
DPDT Switches x2
Quality cardboard (about 2mm thick)
PVA glue
Plastic glue
Paint
Craft knife (I used a small pocket knife)
Soldering iron + solder

Cost:
In all, mine cost me £7 (about $10, I think), £5 for the kit and £2 for the paint. I had all the tools and glues already. If you were buying the motor, this would add another £4 to the cost. It's a cheap and cheerful project, this one!

Step 1: Pre-painting the kit.

This stage is optional, but saves time later on and also results in a better finish. 

Paint all small, non body-coloured parts (such as the prop, wheels and exhausts) while they are still attached to the plastic frame. These parts are glued on later, after the body has been painted and this reduces paint bleed and overlap.

Follow the instructions for the kit until you get to putting the fuselage together. This is when we add the Motor (and lights if you have the space).
Does it blow air forwards or do you have to stay behind it?
It can blow air in either direction due to the reverser switch I included (the slider switch in the photos). I've explained this a bit more in the circuit diagrams. Hope that clears things up a bit :)<br><br>TurboSnail
hello friend, I'm really inspired by this but I have a model plane but I realized it's a et plane then I have another one but it needs two engines . any ideas or tips? thanks so much (-:
<p>Hi, sorry it's taken me a while to read this, but I'm glad you like the project! I don't really know how you would make a miniature jet engine, though that would be really cool! But doing a 2 engine plane shouldn't be too difficult, you just need another motor in parallel with the first one, everything else can be the same. Hope it goes well, be sure to share the results! :)</p><p>TS</p>
Cool.
<p>You've inspired me! Thank you. I'm current working on a model of a B747 and I think I'll have to design a turbojet-engine fan. After all, 4 will be better than one!</p><p>Great Work!</p>
good job <br> <br>
That is a really cool idea i have to make one now.
Very clever idea, and a wonderful desk ornament. But my late father would never forgive me if i didn't mention that you've fitted the undercarriage <em>the wrong way round.</em><br> <br> <br> Sorry....
I am aware of this, but the kit I had had some dodgy moulding parts in it, meaning that the undercarriage wouldn't fit the right way round. I basically couldn't be bothered to modify the parts... <br>Thanks anyway.
It also made concealing the wires easier
Been looking for an excuse to build an Airfix Spitfire for some time! Thank you!!
This is the most awesome idea I've seen in a while. I'm totally going to do this with a P38 or F4U.
Now the challenge is to put a Dyson blade less fan into an Airfix Eurofighter
:)
Im not going to lie, this just made my day, very neat idea. I've never seen it before and I feel like I should have awhile ago!
Cool! Glad u like it. I'm currently working on an r/c version...
This is really cool pal, am going to have to have a go myself. <br>
its great
