heh.. I bet you're looking at the one that's currently on ebay, huh?
my understanding (and I've asked the same exact question here before) is that NO the roadblaster is strictly left to right rotatoin with no "Y" (up and down) rotating i.e. the handles don't turn...
i believe fire fox, turbo sub (prototype game never released), stun runner... all used star wars type yoke... also empire strikes back and of course ROTJ game used the yoke too...
good luck... and happy bidding... I'm now dead set on getting one, so i'll be cruising ebay too =P
