Been flying a Phantom 1 for quite some time now, and recently bought a Phantom 2. I invested in all the cool upgrades, and been flying it 5-6 times with no problems. Then yesterday it just dropped out of the sky from 100 meter up. I think I have solved the mystery, but would like to know if this is a common problem? Do you think DJI will take my complain serious? From what I have read, I shouldn't have high hopes.
