I've wanted to build a small remote control car with a Raspberry Pi and a wireless controller to control it for a while now as a fun little computing project, maybe something like this but bigger and with gears, suspension, a more powerful motor and alike. It would definitely be powered by a motor of some sort and is technically still a car in need of maintenance (and repair if I then crash it)!
Are questions about RC cars off topic for this site? If so, why?
Note: Questions would be related to the assembly of the vehicle - not anything to do with the electronics, programming, shopping advice or anything else like that.
