Concerning the T600 vs T601 issue that has been discussed many times. Today we did again a test, 2 x Inspire Pro, both on FW 1.4, both 658C controllers, one is a T600 and one is T601. Same place, same conditions same everything. The T601 has a MUCH better range, much better penetration, much more solid RC connection. The are area was not very flat and there was some inteference. Buildings, power lines etc around. Where the T600 started to loose image transmission at around 0.6 miles, the T601 flew 1 mile and rock solid signal, not even dropping a bar, even not when turning around. So for those who got shafted by DJI, just like we did as well, the T601 is MUCH better ! Again, this was a real world test, not a 'on paper' thing. So dont buy the BS from DJI when they tell you in real world you will not see any difference.
