While shooting for a sports documentary for HBO, I took time out to try the Go Pro 4 Black with a Steadicam curve. I shot in 4K 24p.

Since my assignment was with C300, Go Pro was for testing and I used it briefly. In couple of shots for sprint, I placed the Go Pro on the ground and ran away to position myself. The framing was off. So I reframed in post and did some ken burns in one of the shots.

Later I did some shooting with the Go Pro 4 and Steadicam in other places (workers carrying sand, boat, wildlife etc) which will edit later. I had ordered the Steadicam Curve to test the Go Pro 4 Black. The first 45 seconds or so is with Steadicam Curve. I am not a steadicam operator. So all of you steadicam operators can get much better than this. http://youtu.be/WWPNPG6vXLI

I think getting good results is not so much up to the operator, it certainly helps out with smoothing out any jitters you otherwise might get when shooting handheld but it not really worthy of the term "steadicam", if you want something better and the same size you are better of getting a 3 axis stabilized gimbal, you still will get some small jitters in the image but mimicking a steadicam movement is much easier as the gimbals will assure your camera stays level at all times.

Regarding framing the gopro, if you use the gopro app on your smartphone you can see whet the camera is seeing, this works quite well.

wow it looks amazing!
