Recently I have been flying the Spark around and notice a delay in the live video on my iPhone 7 and the drone. The gimbal won’t move on the phone and when it does, the video quality gets distorted. This usually happens when it notices WiFi in the way. I have read that the OTG cable can eliminate the need for WiFi between the phone and the RC. It apparently makes the video quality smoother and less choppy. Writing this to know if anyone has experience with this for the iPhone 7 and if anyone can attribute to how well these work.
