Now, the signal strength is better on the DJI RC-N1 over the DJI RC (the first version) as the DJI RC-N1 have the phone holding mechanism that you have to slide out to fit a phone into it that holds the antennas. I have both controllers and have tested it, so I know this pretty well.
The RC Pro however have 4 antennas (2 internal and 2 external). So, the signal will be a bit stronger on it. But the range on the signal from the controllers to the drones are the same within the specification to FAA, EASA and CAA. But you get a better signal strength on the DJI RC Pro and can fly behind trees and such more easily without losing connection.
If you care about not losing connection, then we have the '4G Adapter Dongle' that will give you unlimited range (mostly). And I can use that with my smartphone here in Norway with the 4G dongle attached to my drone (DJI
Mavic 3 Pro). The whole set with the adapter, holder for the adapter and 2 antennas costs around 200 dollars.
As both the DJI RC-N1 and DJI RC Pro uses the same 'OcuSync 03+' technology, you will have the same bitrate on the video transfer speed as far as I'm aware.
Yes, the extra customizable buttons are a nice bonus for some. But I can live easily without those extra few buttons. Everything is mostly easily reachable anyways on my big Z Fold6 screen. It gets clumsier to reach on a smaller screen. I know this as well, because I know how it can be to use the DJI RC with the small 5.5 inch screen (as I have this controller as well) compared to my Z Fold6's screen that has a 7.6-inch screen that I use with the DJI RC-N1 controller.
The 'HDMI' output on the RC Pro is also another nice feature to have.
Not going to deny that the "feeling" of holding the DJI RC Pro might feel better over holding the DJI RC-N1. But the thing that matters is that we already have a good grip and pretty alright feeling on the controller (which I have on my RC-N1).
You have to use a tablet holder for the DJI RC-N1 to be able to use the Z Fold6 / 7 with the DJI RC-N1 controller.
I use this tablet holder:
PGYTECH Tablet Holder V2
So, yes, both the Z Fold6 and 7 will fit in that. Also, the Z Fold7 will be some few grams lighter over the Z Fold6. Z Fold7 is 239 gram.
But the real question is, is those few advantages the DJI RC Pro has worth it when you take into the consideration on how crazy expensive the RC Pro controller is over the RC-N1?
If the RC Pro have had a 7.5 to 8-inch screen, nice OLED screen, at least 1500 nits brightness and have costed like 800 dollars, you could sign me up for buying it.
