- Single solar cell
- transmission: miniature white gears 3:1
- wheels: mini gear & ‘O’-ring tyres
Takes longer to assemble with ’0′ ring wheels. High speeds on smooth flat surfaces with plastic wheels.
The picture shows a 9 mm diameter pinion gear driving 31 mm diameter axle gear, giving transmission ratio 3.4:1 and ‘O’-ring tyres, outside diameter 40 mm.
The motor & transmission sub-assembly is easily removed from the PV cell by opening two pinch terminals and pulling apart Velcro type hook & loop fixing.
5.2:1 transmission ratio
