I just wanted to know if there is any particular reason to upgrade the firmware. Mine is currently on 1.3.20+ for the Phantom and 1.3.20 for the RC. I took it up for the first time this evening to test things out. It fly's awesome. It hovers awesome, no problems with drifting whatsoever. Shot a video with it and it is sharp and crystal clear. So, very happy customer here! I've read all the horror stories people have had from upgrading firmware. I have no need or desire for the "Intelligent Flight Modes. I just enjoy flying it and being able to take awesome video with it. Is there anything that I'm missing other than the Intelligent flight modes, and geofencing crap by staying on 1.3.20?
