That needs forward flight to work. A quad copter does not have a glide ratio high enough that it would be able to start up the rotors to spin fast enough to get some lift out of them. A quad copter is best modeled as a brick with a magic anti gravity device attached, if the anti gravity device fails it is a suspended brick and gravity will soon assert itself.

A real helicopter (or an auto-gyro) is best modeled as a rotating wing, as long as the blades rotate you can control the craft to greater or lesser extent. It still won't be pretty in a proper helicopter but at least you have a chance.
