At the end of the Unsuitables Callum uses one to fly to Bristol to get the dictaphone off the Ranchers to give to the Questers.
The Hot ZoneEdit
He eventually finds the Ranchers camping in a field after they lost the hotel. The paramotor is last seen when Fizzy takes it off them.
It is powered by a large fan mechanism, much like hovercrafts and the parachute is red and white. There is a seat for the occupant to sit on.
