Hi all, I have started this topic as a specific to the radio controller and vision connection. I would be grateful if anyone has had the same issues to post here and discuss. My Pv has had connection issues straight from the box... constantly goes into RTH mode. This happens at various heights and distances but no where near the 300m range advertised. I have lost vertical connection even at 30m, 40m,68m (RTH starts). I have updated the phantom and controller to the very latest updates and have flown in open fields even turning my phone off and flying just the phantom with range extender etc all switched off. Nothing makes any difference! I made the shop aware of this after 5 days. They told me dji were releasing an updated firmware... which I updated. Still no different so I have returned it for repair, replace or refund! Has anyone had the same problems? Thanks, Chris.
