This is my new lift, the Giant K'nex Ball Catapult, it shot to a distance of 4 meters (because my room is too small), it only contains a motor, it's totally automatic, the arm is tracted by a nylon cable, but the shot is very hard to regulate, because the catapult shot creates a role-back, and the elastics extend. But the final result is just awesome !!!

I could give you the instructions for build it, but this lift is (In my opinion) the must dangerous K'nex ball lift ever !

<p>Wonderful!!!</p><p>Please upload instructions.</p>
<p>All right, I can think about it. ( sorry for my bad English :/ )</p>
