Keep your eye on your cellular signal!!! I was using my iPad Mini 4 cellular with Verizon service the other Day in (Follow Me Mode). I got close to a large two story house with my Transmitter with tablet connected, and had my **"VERY FIRST FLY AWAY"**. I've had Hundreds of FLAWLESS flights, with my Biggest issue being a tilted Horizon. I walked towards the Phantom, and it took off FULL SPEED BACKWARDS!!! I "BARLEY" had time to flip my toggle switch back to P-MODE before slamming into some 110FT Pine Trees with a POND Right in front of them. I took it as a lesson learned the BLESSED way!! I only have one Piece of Advice after this Close Call other than insure your cellular signal is EXCELLENT, and that is to make Absolutely Positively Sure your Set to ***(Multiple Flight Modes)*** in the Go App. Atleast Then you can just Flip your switch up in a Emergency, and Exit the Smart Mode. If I had not had that Enabled in the Go App, My Phantom would be swimming with the Fish Right Now. I Consider this a "MUST DO" When using ANY of the Smart Modes, (No Matter What). Most people probably know this, but for the one Fellow Flyer that doesn't, I hope this post may Possibly save them some Heartache, or even Worse.
