Robo Jock,
The intent is that the disks do not tilt. The rotors do not have flapping or teetering hinges and the blades are to have absolutely minimal flex.

I'm not against augmenting inefficient aerodynamics.

The following is from an excellent 20 page article in the latest AHS's Journal. This excerpt is discussing the side-by-side Platt-LePage XR-1. http://www.nasm.si.edu/research/aero..._page_xr-1.htm
"The twin lateral configuration had inherent handling difficulties that the Germans had hidden well -- specifically that in cross-winds, or while maneuvering, one rotor would move through effective transnational lift while the other one had not, causing low-speed lateral instability."
First optimize the aerodynamics ~ Then add the Band-Aid's.

Talking about fixed wing characteristics, I once owned a Grumman Tiger that was placarded against doing stalls; since the stall might put the craft into a flat spin. This might have been a way to evaluate reverse velocity flow over an airfoil. 
The suggested way to exit a flat spin was to get out and stand on the wing.
