Hey guys - hovercraft could prove tricky not to mention fiddly.
Have any of u heard of Wing In Ground effect??
It's like a plane but forces air under the wings which gives lift.

p.s. when I was (a lot) younger I made a crappy hovercraft with a couple 1.5v motors, from one of those styrofoam meat trays your steak comes in from the supermkt, & a plastic cup. :/
((I can hear u all laffin @ me) just hope binarytosser isn't around - don't think I could take it)
