http://www.aliexpress.com/item/Free-to- ... 63626.html I remember seeing the Google Cardboard demo a while ago... Then I thought...what if you just strap your smartphone with an already high resolution display to your face for FPV flying. No cables...no fuss. LOL Not sure if the lenses in this will prohibit you from looking at a regular 2D image (most likely). But you may be able to take out the lens portion so it's looking straight into the phone. Anyway, it's an interesting thought to consider if you want to do FPV on the cheap. It would also make using the gimbal with accelerometer more intuitive.
