downloaded the document and had a very quick scan over it, will read more carefully over the next day or two. would be interested to see your thoughts dave.
still not taken my bnuc-s yet, work and stuff getting in the way, but do still intend to.
as an aside, i spoke, quite by chance, to a couple of experienced rc pilots who have gone down the 'dircet to caa' route for permissions and apparently had positive results.
not something i'm confident in doing, but maybe still an option for the experienced out there with the right connections.
