FSX Scenery–Lumb In Rossendale private airstrip update. Using SbuilderX the terrain mesh has been recreated so you can now set your terain mesh to 100%. Also because this field is so difficult to find in real life a couple of 45 gallon drums have been lit so you can see it quite easily. In real life this field is incredibly bumpy; it’s quite smooth in FSX by comparison. By Neil Birch.
