    How many J of kinetic energy does Phantom produce?

    BTW.: I know your post was old but I was looking for the same info so as I had found out I thought I would answer it. Did you (Claust) get a permit for flying commercially near built-up areas in DK? And if you did - how?

    How many J of kinetic energy does Phantom produce?

    It is very well explained here: http://www.wikihow.com/Calculate-Kinetic-Energy So - for a normal phantom with gimbal and go-pro it would probably be something like: Ex=(2Kg*(10M/s)²)/2 = 100J
