Don't get rid of THRUST... it's a great name and goes great with your guys awesome method of monocoque robot construction and it's aviation heritage.
People's minds invariably hop in and out of the gutter all day long, and I'm sure if people look around
urban dictionary typing in different parts of team names you'll find tons of them can have a 'negative connotation' as you so politically correctly put it.
As a note, personally whenever I reference you guys in conversation (which seems to happen a lot
) I almost always say 'blah blah blah 1501 blah blah' not 'blah blah Team THRUST blah blah blah'. But, none the less, please don't change your team name.
