Hello all. I have a quick question. I am going to be upgrading to a Phantom 3 pro from the Phantom 2. the phantom 2 has been great over the past year or so. But with the more demanding things people are asking me the Phantom 2 has reached its limits to what i can do without adding parts to it. So question i want to ask before it arrives next week is the updating firmware. i was watching DJI's video about firmware and how you have to use a SD card to update it and listen for beeps. Isn't this a step backwards from what i could do with my Phantom 2? I could plug it right into my PC and update it with a USB cable with the Phantom 2 Assistant App. why don't have anything like that for the Phantom 3? If this is the only way you can update it. how often would i have to do this?
