I didn't see this in the other signal loss threads so I thought I'd pass it along.

All of a sudden I started having video loss during flight. It would come and go and did not seem to matter how far away the unit was from the remote. Sometime I would just lose part of a screen but not the whole image. Never lost control of the unit and recorded video had no hiccups.

Finally realized USB cable to iPhone had gotten wrapped around the antenna. Once I unwrapped it and moved it away from the antenna it has been rock solid. I know. Rookie mistake.

I purchased a nice gold 12" cable off Amazon ( http://www.amazon.com/gp/product/B00P76UFDO ) which works great with the RC and my iPad Mini 3.  The ONLY time I get video feed loss is when the P3 is processing/saving an HDR photo - other than that no dropped video feed at all.

Thanks for sharing I didn't know that.  I will be careful with the cord.
