You can buy kits in various forms from completely assembled and ready for fuelling to kits where you have to decide how to
assemble them and what engines to fit.

The first thing to do of course is to choose the car kit you want to build.

There are hundreds for sale on this site (usually at far less than store prices)

There are almost as many thrills driving a high performance RC car at speeds of up to 70 mph and acceleration of zero to 60 mph in under 6 seconds

It is just so easy to operate an rc electric car.
You put batteries in – turn the switch and it goes beautifully.
