I have the standard FC40 with the standard clamp that is attached to the controller. The clamp open measured to allow a 3.5" WiFi pocket tablet to fit. The 7" diagonal WiFi tablets/phones are all too large for this standard clamp. So, has anyone made a list of what WiFi tablets WILL FIT that clamp??? Seems these are sub-7" units, usually 4-5" diagonal screens. Not even the clamp manufacturer has provided a list I could find showing why they picked the size they did. My own tablet is a 10" diagonal and so looking to find a used 4-5" diagonal I might use just for FPV with the standard FC40. Any ideas???
