An interesting side note... When he built his version of the Toucan forward swept flying wing, MAN Editor Tom Atwood added a rudder control just to see what it would do. Since you should, theoretically, get reverse roll with rudder on a forward swept wing, he thought it would be very interesting.

In flight - nothing. Nada, zip, zero, bupkas. The airplane yawed a bit, and proceeded to fly straight and level with no correction required. Strange!!
