Hi Simon / @Montocat , and welcome to GADC.
We have a growing number of members who are into self-builds … to the extent that the #racing-quads-self-bulilds-and-fpv section was added recently.
If you haven’t already, take a look at the Map of Members and you’ll see there are a few other members in your neck of the wood.
(Don’t forget to add yourself to that map 
: How to add yourself to the Members Map )
Also, if you’ve not seen it, check out our map of places where members have flown in the past … which, obviously, doesn’t necessarily mean they are still OK to fly and, as always, any pilot needs to check that everything’s OK before flying at any of them.
