I recently bought a Fly6 and am generally very happy with it. The only issue I have is that my saddle bag obscures the top of the view. I ride a large frame with a lot of seat post available compared to most and still find it difficult to get a good position for the camera. If the lens was at the bottom of the unit instead of the top it would solve this issue. I can't see why this wouldn't be possible?

Have the device auto-rotate the image as the front camera does.
