In the electronics box there are the following items
On the far left in the base of the box there are three electronic switchers running off one radio channel, these switch on the lights, first the navigation lights, then the bridge house, bridge house desks lights and rear hanger lights and finally the fore and aft flood lights.
On the centre and right the are two sets of electronic controls that power the two radar drive motors, each system consists of a variable voltage regulator (1.5 to 5.5volts) followed by a speed controller - the speed controller is a pulse width modulation system (like modern motor speed controllers) and the frequency and pulse width can be both adjusted in oder to achieve the correct rotational speed.
On the top of the box is the sound system, this consists of two oscillators one producing a deep horn sound the other produces the Whoop - Whoop siren sound, the output stages are linked together to drive one speaker.
Hope this gives an idear of whats in the box, any more questions just ask, If you would like to see more pictures I have loads, I kept a photgraphic diary of the build.
