Forward swept wing?
stick,
I haven't read all the replies yet, so I hope I don't repeat too much. From a stability perspective, forward sweep is destabilizing in pitch and anhedral is destabilizing in roll. The amount of anhedral shown in your sketch looks pretty modest to me, and could be reduced if needed by extending the gear struts a bit. I am tempted to say that there is no effective forward sweep at all, since the horizontal stabilizers are coupled to the wing at the forward most point, but I am not sure that is valid. The only thing that strikes me as a possible issue is the fairly small tail volume. You might have an easier time if your booms were longer.
Good luck,
