…is what DD8 has asked for. I think it’s something she’s come up with herself rather than spotted. Does such a thing exist?
I can find build-a-car/engine kits, and I can find remote controlled cars, but not something that combines both (and that an 8 yr old could do).
Her other request is a snood which is much more manageable 
This thread is a little old now so some of the suggestions may be out of date, but if you’ve landed here looking for a great remote control car, we’ve recently updated our best RC cars page with lots of great options, as tried and tested by Mumsnet users and their kids. We hope you find it useful.
