** Free fall tower ** 
*********************

* Still no lift system implemented. Might go for a self build air piston to propell this baby with 
  high air pressure and give it some launch velocity.

* Wagon still isn't stiff enough. Bends/moves a bit. 

* Friction Break system runs with a pneumatic piston. Two of those 
  beauties are good to stop the wagon and 2 lego motors from a 2meter drop. 
  Adding a rubber band to the break shoe will increase the delay.
