Two electric motors with 24 Volt power and speed controller is the answer to your question Alex.
Real life toys supply a manual with instruction on how to make this model from two 4X8s of either plywood or moisture resistant MDF.
For those of you still in the UK they will also supply pre-cut panels.
Most of the hardware- lamps, grille, steering wheel, wheels and latches for the tailgate etc are from RLT, though some make their own parts.
One person did a cost comparison and apparently there was a GB 150 difference between buying vs making your own. (cheaper to make your own)
AS for the landrover badges and the AA badge these are made by a guy in Northern Ireland with CNC technology- I ordered those separately.
Good luck to anyone who embarks on this project for their child it is a very worthwhile project. It felt good to hand over the keys to the new owner. Not many 4 year olds drive hand made electric cars!!
I can say that for someone who does not do woodworking/ carpentry or electrical work for a living this project was a massive challenge and I learned alot along the way, and with some help (thanks to all who offered their advice) I am near completion. ON Saturday we got all the indicators working, the headlights work and the brake light comes on if the car slows significantly. Just some cosmetic fixes to do then should be able to move onto the next project....
Finding room for the cars in the garage!!!
