There is some merit in this conversation, starter kits, initial contact arousal's,
I have never seen anything in Australia like radio controlled model landys. These were around in popular mechanics eons ago, simple, easy, cheap and they make the initial connection with much needed parent sibling participation. "From little things, big things grow". Could be a good affordable promotional point for schools, the limpet point.
The next step is similar to what happened in the canoe industry. From the original old cumbersome Canadian type canoes " read blown cart " to the Roto moulded heavy duty plastic non destructible' wild man, solo style.
This could be the entry level man carrying capable, less injurious and nearly indestructible, cost effective, have a go matey, starter. No welding skills, just goooo!!!
