I recently got a Hubsan X4 FPV kit. After the first flight I took it apart to find out…”why is this so HEAVY?!”.
It comes apart with just a few screws on the bottom. The arms are snapped together so just un-snap the top and bottom halves. Comes apart very easily, but watch out for the ribbon cable which still holds the two halves together.
I’ve added a wide angle lens to the camera with 3M extreme outdoor mounting tape. This makes the quad much better for FPV, the standard camera field of view is way too narrow. What’s the tradeoff? Well now it’s even heavier than before! Really difficult to control compared to the featherweight Nano QX.
