Landing problem

[Montermini]

Hi guys,
I've just bought a new dji phantom 3 standard. After the pre-landing controls and the calibration, I've tried many times to do the automatic landing but everytimes after few seconds the RC doesn't respond anymore, the RC light starts flashing red light and it disconects from drone. With a manual landing the drone dosen't stay stalled but it moves horizzontally even if the RC is giving him a neutral position. Do you have an idea of what Can I do to resolve this "beginning" problem?
Thanks for helping.

It may sounds basic but here a few things: Is your RC antenna pointing to the Aircraft? Shouldn't be! It should be at least perpendicular to the line between the RC and the AC. As far as the instability at landing, are you landing in ATTI mode or GPS mode?
