Hey Mickjoebill
I read your description, watched it, then read it again, but I still don't get what you mean?!
I couldn't get the mindset out that the helo started moving backwards and i can't picture what you're saying? What way did he turn 180?
Is the camera UNDERNEATH the helo? If so, then i totally get what you mean,
(and that may sound like a silly question but we don't have this stuff over here, lol!!)
