I have yet to purchase an Inspire. I'm about to, though I'm literally just holding off for maybe another month having been burnt by the initial release of the phantom Vision back in Nov 13. I shall be completing the required qualifications to use it commercially here in the UK once I eventually make the purchase. Im after advice: I have been asked by a friend down in the south of England if this machine is capable of flying indoors safely as he is in charge of the maintanance of a cathedral and would be interested in using a UAV to photograph a number of stained glass windows. These windows are pretty high up but there is lots of space around them. There will be no members of the public in the cathedral whilst the operation is taking place and insurances will be in place. Obviously GPS will not be available but will the Inspire positioning system work at such a high level? (I'm thinking not) it's probably going to be working at heights between 80 and 120 ft. Comments and suggestions please.
