Answer 1

The biggest advantage of a quadcopter is stability. For a cheap (or expensive) toy, it makes sense to quadruple the parts so users can enjoy it out of the box with little to no training. With a very expensive functional tool, you can expect serious training for the operator and can get the same stability with lower costs of production and maintenance in addition to fewer points of failure.
