Pine wood derby cars

Hello,
Im thinking about offering to carve cars for kids this year. Looking for any idea or suggestions to streamline the process. Im planning on sticking only to easel and want them to be able to draw out a design on a template and then bring that into the computer. The biggest issue is the oldest kids are only 10. I still have nightmares about teaching them to tie knots and whittle. so yea any ideas will be appreciated.

alot of these concepts can be done on the x-carve

Thanks guys. I’m looking for just easel design ideas no gcode. Phil I don’t remember is your bat mobile 3d. These kids have little to no cad knowledge.
