Unless the fit of the casing parts is atrocious, there appears to be a slit right above the grey ring the camera is mounted in. Due to the shape, and it's location it's quite possible that internal shutters or ducts can be configured so as to allow partially disrupting the coanda effect on either side by selectively allowing air to exit through the slit. Possibly, but not necessarily ducted in from the fans high pressure zone. This would likely cause a rather strong vectoring of the thrust as it would also almost certainly lower the lift on the detached side due to interactions with the fans. If that isn't how its done, I'm quite positive it can be done in this way. I'll be happy to be named inventor in any thusly aquired patent and collect a very modest licensing fee, if only that would be how the world works...
