The prototype body looks fairly simple to replicate so it should work well to house everything you need.

Thanks for your reply. Yes I suppose it will fit al under the passenger bench hopefully. :)

Some progress on the chassis. I used an other plywood part leftover and and a sheet of balsa on top.
Also made an axle mount out of styrene sheets. Again all very basic and light.

Best to use a schottky diode as they have less voltage drop. Any normal diode will work though provided the solar cell voltage is high enough.
Can a LED also be used for blocking diode to prevent discharge? It is a Light Emitting Diode so I suggest it could?
That would be practical as I can use it as light :scratch: :idea:
Or would that LED only be working when charging?

The forward voltage of a LED is a lot higher than that of a normal diode so probably not a good idea. You would also need a current limiting resistor in the circuit so you don't fry the LED.
