Step 2: The Electronics.
This is a simple bit of wiring and took me 5 minutes max. Wire together the motor and a switch, using a reverser if you want. I used one so I could have the Spitfire in fan mode (pushing air away) or in realistic mode (i.e. the prop going the right way). This is made from a DPDT slider switch, as shown in the diagram. The lighting circuit uses LEDs powered by a 9v Cell and the Motor from a 1.5v AA cell, hence the DPDT toggle switch used to turn both circuits on. I eventually left the lights out of my Spitfire, purely due to size issues as I didn't have fine enough wire to fit into the slim wings.
