Out of the box my 4K dropped video feed after about a minute or so. I know I'm in a congested wifi area, so I assumed that was the issue. I just purchased a 2nd ST10+ with the Carolina Dronz antenna mod. 1st test flight with new xmitter and after a minure it dropped the feed. I snapped a few photos and it froze on the last photo. Will the antenna mod cure a heavy wifi area? Or is it same results with booster or not? I'm now thinking the problem is with the camera or quad. Thoughts? What are odds I have 2 bad ST10, one with the antenna mod. ?? Thanks for any help / thoughts.
