I would totally recommend the Itelite antenna upgrade. Made me feel like my Q500 was now a real camera drone platform that I could rely on. Before the mod I was very disappointed in the birds range and video feed. But now it is solid! Also Carolina drones external 5.8GHz camera gimbal upgrade kit made things even better. But I have not even wanted or needed to upgrade the internal 2.4GHz antenna's. My Q500 transmits telemetry long after I lose visual sighting of it. After I lose my video I can not set up shots anyway. So no need to fly so far. I have flown my Drone to it's battery limits, and just barely made it back to base. So if you want to fly farther then your battery will last...well that will just be a bad Idea in my opinion.
