Helicopter
4/25/2017
» requires variable pitch blades / swashplate> change thrust vector
» requires tail rotor> compensate torque by main rotor
» requires gearbox> high engine RPM
» single-rotor
» requires lots of mechanical parts
» fossil fuel-based engine> loud, low efficiency

Multi-rotor
4/25/2017
» fixed pitch blades> no swashplate required
» pairs of counter-rotating rotors> no tail rotor required
» no mechanical parts(except bearings)
» small rotors (at least 4)
Multicopter (model)
» direct drive> no gearbox required
» electric motor> low noise, high efficiency
