Do you have a Phantom 3 Standard and don’t get as much range as you would like?
There is a solution without breaking the bank, a cheap range extender that should be able to get to a mile/1,5km out.
It costs a few Euro’s/dollars but it is worth the money! You can get one here
Currently I can get over 400 meter without any problems or messages, this is stock, and I haven’t tried to get further out, might even get further.
But I will post the new results soon! I bet it will go a km at least!
