They didn't make it clear in the interview if they'd solved the imaging problem or not yet. How do you get usable video (or stills) back from a camera that's rotating constantly - and potentially, erratically.
Counter-rotating the image, synced to the rotational speed of the device, would seem to be a simple solution, provided the camera was centered i.e. it wasn't constantly panning.
Even if it was (e.g. mounted on the fastest-moving outer edge of the wing), software could reconstruct a panoramic view. You don't even need to align images from subsequent rotations, if you know what direction it is pointed. You'd get fps related to RPM though.
