Hi NeoNeo, appreciate your detailed reply. You asked "Were you using a smart phone as a controller or RC2" and to be honest I cannot rember but we were using either the DJI RC-N3 Remote Controller or the Goggles 3 and RCMotion3. My friend may have been using the RC 2 controller.
You said "when using Goggle3 and probably N3 there is an option in the Menu to switch from auto to a specific channel" which I didnt know. I'm going to tell my friend too. Good info for sure.
So thanks again, we will try your suggestions and use your information.
We went out today and didnt have any problems. I did notice a message in my googles that said "interference detected" when he flew hid Avata over me, but I had no loss of control of the drone.
We were also thinking maybe he didn't have enough satellites before taking off because his drone went crazy as soon as he took off.
Thanks again for the help and suggestions. There really appreciated!
