I bought my son (31yo ) the GoPro Karma for his birthday and after downloading the updates and calibrating and he used the flight simulator to practice we all went outside to enjoy his first flight. Everything went well at takeoff. Went up about 50 feet and starting roaming to the right by it's self but got it to come back but just then it took off like a bat out of hell and with no response from the controller just watched $1000 fly out of sight. We spent New Years Eve in the woods trying to locate it's last known location. Happy New Year Karma I just spent $1000 for 5 min of excitement and 4 hrs of searching.
