Last experiment: Rudder hinge line now at even 45 degrees.
Net sidewash from rudder trailing edge again a bit more upwards (compare how the arrow heads are above the wing).
The effects on the horizontal tail seem to be bigger at more sweep, more downwash left and less right.
Rudder moment again smaller with more sweep. Maybe that's why aerobats have vertical rudder, it's substantially more effective (-0.0118 swept 45°, -0.0193 unswept). I didn't find an explanation of this parameter yet so I'm not sure if it's really effect or simply the "shorter" rudder moment arm.
