In the case of helicopters, when you spin the rotor one direction, the body of the helicopter begins to spin the other direction, which is why real helicopters have a tail rotor mounted sideways. Coordinating that in an R/C helicopter is simply too complicated. If you instead mount a second main rotor spinning the opposite way at the same speed, Newton's Law is satisfied and you don't have to keep making minor adjustments to the helicopter's heading.
