This my second design of the tank. My first design looked too much like a car. This is my second instructable

Step 1: Parts

Rods

ETC

Step 2: Wheels and Motor

Make the parts as shown. Set aside.

Step 3: Sides

Step 4: Putting the Wheels and Motor Together With the Sides.

Step 5: Gun Turret

Make the turret as shown.

Step 6: Attaching the Turret

Attach as shown.

Step 7: Firing

Remove the yellow rod from the green connector and flip it up. Pull the orange connector back until the rip is past the space between the yellow and gray connectors. Then flip the green connector into the way of the rod so it stays in place. To fire remove the green connector from being in the way. It can fire white or blue rods. If the orange connector comes off, just reattach it.
