Hello, I have a phantom 2 vision (no camera and no remote control) and I have a remote controlled of phantom 2 (2.4ghz with receiver), question ... I can use the remote controlled of phantom 2 (2.4ghz) in phantom 2 vision, only changing the receiver? , sorry for my bad English.

Hi,

Please remove the WIFI module before you use your P2V+ with 2,4GHz controller. The WIFI module uses the same frequency to stream video to a phone/tablet.

You can also buy a 5,8GHz controller from DJI: https://store.dji.com/product/5-8g-radio-controller-npvt

He has the Vision, not the Vision + and I think the Wi-Fi unit for the Vision is in the camera body, which he does not have.
So yes you can change the receiver to 2.4GHz, but then you will not be able to put the Vision camera back on later.
