Re: I built one at uni
I definitely built a model hovercraft like the first ones in my school days in the early 1960s - possibly two. An Airfix kit and one made of balsa. As I couldn't afford a diesel engine then the latter was unpowered.
There was a more recent charity shop buy of one that would fly. I possibly gave it to another charity shop after the neighbours' youngsters expressed no interest in having it.*** Although it might still be in my "interesting toys" box.
***The only things that are guaranteed to take their fancy, both boys and girls, are fast R/C cars - and water guns. Electrical, electronic, and computer controlled devices seem to have no attraction - apart from them admiring my Halloween effects. ... but no query as to "how do you do that?"
