Get a good raw powered weapon (eg wyvern agito - what I used for the guild one) and tripple charge on the stomach. If you hit anywhere else he will not be injured enough to repell.

If he starts attacking the fortress on the ground more often It may mean you are on for a kill, so carry on hitting the stomach. If you need to stop him attach the face as it staggers faster.

With lance the stratergy is much the same, just upstab him instead.
