I have read thread upon thread , I just don't see one like my situation. I have linked controller, have all the updates as far as I can see.
When I try to take off.... it reads " Warning--- COMMAND TIMEOUT"
No It didn't happen right away. I flew it from Dec 2015 ( Christmas)--- Memorial day 2016 with no problems. Then it wanted updated, not sure now if it was RC or drone update. I ran the update and it jusat locked up and wouldn't finish. So I exited the App and its never worked since.
