The Draganflyer has been successfully converted from brushed motors to brushless motors. This conversion can be done for approximately $220. The advantages of the conversion are:

1) An increase of 2x to 3x payload capacity.
2) Longer flying time for a given payload.
3) No fragile DC motor wires to protect.
4) Smoother hovering
5) Higher power for more controlled descents with heavy payloads

Here is a video of the first test flight carrying a 21 oz payload:
