Don’t get confused between Airspaces and No Fly Zones. The vast majority of the UK is covered by controlled airspaces of one classification or another. You are permitted to fly within certain airspace’s but with any DJI craft the firmware will severely limit you within NFZ areas - the nearer to the centre, the more severe it is.
Looking at your map I would say that the craft will fly legally around Mawgan Porth, within a NFZ but not within the inner red circle, but the firmware will limit it.
One query here. Say if I’m up in the Grampians sometimes the RAF come Zooming past in their jets what height do these guys fly because I know it’s very low.
