I have another idea for an interesting test using air tanks. Set up a pneumatic
engine and add an extra piston to ONE side. (so there are three total pistons,
and two move at the same time) See show the speed compairs with vs without
airtanks.
This will start to simulate how SSClagorpion works.
Next, I want to make up a work schedule, to see if we can complete this thing
before Brickfest.
