colorex- a flying wing in general I wouldn't recommend for a complete beginner. Once you've been flying trainers a little while and have your orientation issues worked out they are not really any more difficult to fly than any other plane.
Having said all that, if the wing is built light so it slows down well and you have an experienced pilot to help you out you can and I know several people that have learned to fly with a flying wing.
My 2 cents, start with a trainer
