I have the RC Pro & it is a huge step up in performance compared to my
M2P &
Smart Controller V1, very smooth, no crashes (software!) but as I'm in UK it's limited to CE power outputs & I have had a few disconnects when the
M3 goes just a touch too low behind a dense patch of old trees near me, especially when they are wet. I tried using the original RC-1 controller that came with my
M3 & used my Samsung S9+ so the screen size is almost the same as the RC-Pro, the benefit of using my phone was I could load in a modified version of DJI-Fly that enables my
M3 to fly with FCC power outputs which makes a big difference when behind the same section of trees, now getting no disconnects so eagerly awaiting the day when I can do the same hack to the RC-Pro.
