I'm still in,y first week of flying, but I am very nervous about taking this thing up high. I keep getting a "controller signal lost" message when it gets to about 150 feet. And this is just straight up, not way off in the distance. As soon as I see that I move the stick down and it starts coming down. I'm a bit confused. I wonder if it really lost the signal, or if it was just brief. Maybe antenna is positioned wrong? Also, is there a way I can make it return home other than turning off the remote? This thing is fun, but it's a little stressful too.
