The Hexa certainly can carry a DSLR, I would recommend anything up to a 7D size, I probably would leave 5D flying to an Octo. So popular cameras like the Sony Nex series or Panasonic GH2 are no sweat.
Hexa is sold, updated Octo pricing now to include the JR 9503 radio. Also throwing in a free Navi 2.0 board if you want to upgrade it to the latest and greatest!
