Kits to build with my son.

[breamster]

Hi,

I would like some sort of kit I can build with my 5 year old? The more practical the better - i.e. not an airfix kit.

I've been looking at stirling engine kits, the haynes engine etc. Ideally, a nuts and bolts type build rather than scalpel, glue and paint. I've built a few of the balsa wood models with him and I think they have run their course.

Budget is probably sub £30 but will go above for something a bit special.

A mini stationary steam engine would be superb but I've not seen one in budget.

Any ideas?

Thanks,
