well it all depends on design, you could probably make a 1 rotor copter out do a 2 rotor copter much more easilybut having 2 rotors would make the heli not stay in the air as long as a heli with 1 rotor, right?
a good design tip is to make things as simple as possible and adding another rotor is only going to complicate things
if you have used the right design it works,,,,,,
