Have P2,3D gimbal, 10"HD monitor ( to help eyesight). What attracts me most is the HD video transmission (and price) because: With the 10" monitor as is now, I can see details as never before, but when I plug the gopro directly by hdmi to the monitor after a flight, the detail improves so much you never want to go back. You can now see power lines clearly as well as other potential hazards at great distances, which improves operational safety (it just looks so clear) But according to my son, both Pro and Advanced only transmit the video signal back down in 720p, still good enough for advantages listed above. If this is true then I would lean toward the cheaper option. But I know how great 4k looks on a big TV - stunning, so if video shot in 4k on this camera, will it show 4k resolution on the 4k tv? If so, there's one of your incentives, it would be stunning and the final viewing to me is the most critical, the fpv part would be great if 10" 4k monitors were available, but don't think it would add very much additional hazard sightings ( though would look great - 4k googles yet?). As my eyes get older, I'm already thinking of mounting my computer's 40" HD monitor to back of golf cart where the seat spins around once cart reached destination flying area, and operate drone from the shaded comfy seat, and can follow drone when and if terrain allows (may use drone to search for my ball that has never seen a fairway - and you thought drones were a expensive hobby) capg
