Hey. I have a TonFly CC1 with the CX100 box + zskulls for both top and side mount. I use the same box for both top and side, depending on what jump and angle I need or if I add my still cam as well.
Here's a link with a photo from top mounted, don't have the side mount pics online yet but will see if I can get one during this week.

By the way, the top mount works well for reversing your cx box - per example for shooting base exit and getting the jumpers above + the cliff nice and centered. Anders
