VR is a must in a helicopter.
I disagree, from my own personal experience. The key thing is fast shutter speed, such as 1/2,000s to 1/4000s. Here's why. The VR will never be able to cope with the rapid vibrations from a helicopter. Also, keep in mind that VR only works at speeds up to something like 1/500. Past that and it can't sample and react fast enough. Often, the VR will actually hurt sharpness at speeds much over 1/500s. The whole thing is to have a FAST shutter speed when on a plane. Also don't forget you are coping with motion blur of the ground unless you are hovering.
One other thing I forgot. Don't let the camera/lens touch the window or anything solid. Vibrations will be transmitted. What does work is to have one of those cheap flexible black rubber lenshoods on the camera. Press that against the window to cut out reflections. I still advise black gloves, long sleeved black shirt, and even a black ski mask if shooting out a window.
