Do not touch the 4drc
Set everything up by the book. I was in a big field and I was practicing hovering, around 6 to 8 feet. I was nowhere near the throttle, just turns to get the hang of it. All of a sudden it shot up to around 40 feet and off it went. Did not respond to any controls. It disappeared, I've still not found it. £200 down. Company do not respond to my emails. I've since seen on YouTube others having the same problem.
