A propulsion system for an aerial vehicle or toy aerial vehicle is disclosed. The system comprises a ducted fan or shrouded propeller drive system for driving the vehicle along ground, the ducted fan or shrouded propeller drive system operating in a plane and having a peripheral ground-engagement part or hubless wheel. The system further comprises a ducted fan or shrouded propeller comprising one or more blades rotatable about a ducted fan or shrouded propeller axis for producing thrust, wherein the ducted fan or shrouded propeller is mounted as such that it may tilt or rotate so that during ground travel it may be in the same plane as the hubless wheel and during operation of the ducted fan or shrouded propeller for flight the blades pass through the plane and inside the hubless wheel. In this way, the ducted fan or shrouded propeller blades of the drive system are protected from blade strikes on obstacles and personnel operating around the ducted fan or shrouded propeller drive system are protected from harm from exposed rotors or blades with no duct or shroud surrounding them.
