Im new to the site and have found some very interesting info on these phantom 2 non vision drones. Here is my question and once again im new to the drone world so any help is appreciated. I purchased a phantom 2 non vision with the 3d gimbal and have a go pro hero 3 already. I want tp be able to fly 2 miles or more and be able to have full control and vision. Please point me in the right direction on what all to purchase to achieve this without doing it twice. Also flying this far, will the return to home feature still work. I live in the midwest of illinois so everything is pretty much flat farm ground. THANKS A MILLION
