Hi, in the thread "Phones that work well with DJI GO and the Mavic" you say The remote controller mount can only hold devices that are up to 6.29 inches tall" .. but I have been using a Google Nexus 7 (2013) with no problems .. its corners go into the openings in the clamps and the whole fits snugly against the controller. It is 20cm tall (7 7/8 inches). So where does the 6.29 number come from?
