Took my new bag on an excursion today and it did a wonderful job. The foam cutouts are very precisely machined with an emphasis on batteries (it will hold seven). The fabric used in the pack itself seems quite durable and stood up to the multiple branches I dodged today. The zippers (while plastic) are of a heavier gauge and seem to be up to the job, but the highlight of this pack for me is the many-many pockets. I pack an eight inch tablet for flight and a 13 inch laptop for playback as well as all the other goodies a Phantom pilot packs. This puppy has pockets I haven't even filled yet! Had to do a little router work cause I have detachable prop guard brackets on my bird, but it was a piece of cake. Great pack and fantastic customer support
