I have a phantom 1.1.1 and have found that my range seems to be rather short....couple hundred feet. Most times (but not all) when then the quad reaches a 200-300 feet, it goes into failsafe mode. Today was particularly bad and it was going into falesafe at about 100 feet, but today was also exteemly windy, but I can't imagine that would effect radio waves. I am using the stock DJI tx. The only mods I've done is to add a 5k pot for the gimbal control. Is my only option to go to a better rx/tx like the t8j or dx8i, or is there something I can do or check for until my wallet recovers from my last whim. Also, I am noticing a lot more movement when i am off the controls than I see in a lot of the videos I see on line. Typically something like a 10ft radius around what ever point it should be holding at. Could that indicate something? I have done the calibration dance several times and the connection to the GPS antenna seems ok..
