A motor can seperately power a fan that blows either in a forward movement or reverse movement. The air can be projected towards a direction with blades/rudders. The combination of both a fan blowing towards the ground (creating lift), and an upright fan blowing to create movement can make a hovercraft "go"
a hovercraft can go upto 60 mph
no.
Sir Christopher Cockerell is usually credited for inventing the hovercraft.
Yes

a hovercraft can go upto 60 mph
Any reasonably level surface.
The crashed saucer Excalibur is in the mud past the Mill. Use the hovercraft to reach it. To get to the hovercraft in the attic of the mill, pull the rope to unlock the gears. Then go outside and turn the windmill arms by jumping on them. When they turn counterclockwise, the roof dome will open. Add manure to the hovercraft and it will go to the swamp. Get the hovercraft working and you can go out into the mud swamp. (see related question)
While helium can provide buoyancy, it would not be practical for creating a hovercraft. Hovercraft rely on an air cushion from a fan or propeller to lift them off the ground, not just buoyancy like a balloon. Helium's properties wouldn't allow for the necessary control and maneuverability of a hovercraft.
you can't use that if you want a good hovercraft!
a homemade hovercraft works by using using a battery powered leaf blower to find out more please go to amasci (see related link) and in search box type in homemade hovercrafts in capital letters there it will show how to make one and everything you need to make it
There are many hovercraft available for different applications, for example leisure hovercraft, rescue hovercraft, commercial hovercraft - hovercraft come in all sizes, from racing through to leisure and large military hovercraft.
