Hey Guys, On my 2nd day of flying and have a few questions. First question, after I have landed, turned off the battery, inserted a new, powered on, wait for IMU to warm up, I then move both sticks down and inward to arm the motors I get a voice command stating LANDING and motors do not arm, happened twice so far. Tried to use my phone to take off and after sliding the icon, nothing happens...go to try and arm again and hear LANDING. Only way I'm able to overcome is by powering down the battery a second time and for whatever reason it works fine after this. Any ideas? Second question, occasionally I see some type of error message on my phone that says something about a firmware mismatch but it goes away before I can figure it out and when I look deeper I see something that says firmware is up to date.....any ideas? Also would like to know how good the sonar is at avoiding wires and power lines? Unit does great on big solid objects such as buildings and trees but to wires beat the systems? Appreciate any help and advice.
