Step 6: Your Done!!!!!!!!!!!!

You are finally done!!!!!!! The tank likes to go over a big mound of knex rods but dosn't like to go on tile and slippery surfaces like that. You also need to use the motor in picture 3. If you flip over the tank it can also serve as a mini conveyor belt. That is what it was before until I found out it could be a tank. That's why it looks so bad. You don't need to use the red 90 degree pieces on the tracks. Enjoy!!!!!
