Welcome Chris
On FB, we have "Scottish Off-Road Rc" - it's a closed group but Martin will add you - just ping a Join request on the site.
Dunfermline run GT12, plus anything(!) else in a hall on Sunday nights, and a purpose built outdoor facility near Cardenden in Fife. Head over to
www.ddrcc.co.uk for more details.
"DDRCC Racers" is their FB page - search for that.
Falkirk run a winter series which starts this weekend, it's once a month indoors on a multi-surface, but there's some discussion about this going to all-carpet - hmm (undecided). You'll find them on FB too at "Falkirk Radio Car Club (FRCC)" (Public)

There a few others further afield but that gives you a bit more detail to get you going. Looking forward to saying hello sometime.
