The Mavic 4 Pro has an advertised range of over 18 miles. Theoretically. Do you need the RC Pro 2 to achieve this range, or will the current RC Pro controller get the same range?
The RC 2 is also only OS 4 and not OS 4+ like the RC Pro 2., so the range on the RC Pro 2 is slightly better than on the RC 2. However, as a practical matter, I doubt you'd see the difference, unless flying suicide missions!
