Hi Guys Just bench testing my new Vision before first flight (and after following the forum for a few months). The only problem I have encountered so far is that the camera view on the iPhone is very slow to update - several seconds of lag. I am using a 3 year old iPhone 4, and my Vision appears to be one of the earlier ones because the USB is inside the transmitter. I can't update the camera firmware yet as I don't have a microSD adapter. Has anyone else seen or heard of a similar issue?
