Tuna,
The above is the exact opposite of what just about every other Chinese hobby product manufacturer does. In fact, many of them plaster the web with the merits and qualities of their products months before they are released, or send a steady stream of video trailers out to every customer's e-mail that has ever bought anything from them. No, I don't think that's the right thing to do either, but if you want to sell something you need to provide a reason to buy. You can easily say you are holding a diamond in your hand worth millions that you have up for sale but until people see and inspect it you'll never sell it. With the 520, a system advertised to be an inspection and mapping rig that has been fitted with new camera models, touting the merits of the geo referencing system, something available to anyone that builds an aircraft using an APM, Pixhawk, or PX4 FC without also demonstrating the qualities of the cameras is going off a little half cocked. Lest we forget, if the imagery is bunk so goes the data collected during the inspection and mapping processes.
