Right under neath the camera plate. I made a space just for itI was just worry about having enough space for the hdmi cable sticking out of the back of the Epic...I am also considering getting Wood Cam C box converter to stick at the end of the Epic which has a spot on top to mount the paralinx directly (and a built in sdi to hdmi and vice versa...hopefully is doens't make the camera too long to be compatible with the Helix.)
