i guess i never understood why anyone would install a piller that far from
the equator. (it spins like a top, on a vertical axis, and the angular
momentum is really quite gigantic for its size -- it's heavy and it spins
really really fast -- and i remember asking a piller tech why his machine
wasn't tipped slightly southward to account for Coriolis, and he said i was
confused. probably i am.) but for north america, whenever i had a choice,
i chose hitec. (which spins with an axis parallel to gravity.)
