Does anybody here have any experience with any of the numerous aftermarket Chinese brushless gimbals available on eBay such as this one: http://www.ebay.com/itm/DJI-Phantom-Bru ... 4174bde540 Some say they come with no manual, I wonder if you need to be a rocket scientist to connect them, or if the control board works independently of the Phantom. I am wondering also if there is an option with these of panning the tilt down in flight using the 7th channel. Looks like an advantage of these is that they work with GoPro 1,2, or 3. I use the Hero 2 and have virtually no trouble with jello in my videos. In addition, YouTube has an option for image stabilization which takes about as long to process as the original upload, and seems to work fairly well.
