No laws .... but....
Parks and other council owned open spaces can prohibit all sorts of things, including RC cars. Any such bylaw restriction should be posted at the entrance.
Mostly, though, it's down to common sense.
If you run an unsilenced Dominator and rag it around next to people's houses/gardens, you may get noise complaints. The Police may get called, and you may be asked to stop. Sensible running and behaviour, not damaging stuff, and not running close to people/dogs etc. arte usually enough to avoid any issues.
