I built a mount very similar to this. Word of warning: this only works well if the handle you are using is one of the hard triangle type (I think mostly claim to be carbon fiber). If your handle has soft or flexible sides to the triangle connecting the rope to the handle, the camera mount twists. Since the weight of the camera is on top and wants to swing down below, every time you jump or hit a bump there is a tendency for the camera to wobble (almost violently at times) side to side creating a large amount of camera shake. I think this would be corrected with a hard triangle handle as then there is a solid connection all the way from your handle to the gopro.
Also: build two safety mechanisms to protect from losing the camera. One, attach a gopro float and secure with a bead of aquaseal glue around the three sides away from the housing latch (be careful not to let any glue run into the seal). Two, add a hole near the camera mount where you can attach a leash. On my trial run I crashed hard enough it tore the gopro float off the 3m sticky pad. I got lucky that the tripod mount didn't break off as I didn't have a leash as backup.
