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>Wow superbe idee</p>
<p>Thanks, I actually make instructions for build a V2.</p>
<p>This is actually pretty awesome. Regardless if you post instructions or not, real well done. Didn't think such torque could be achieved with a standard red motor (mind me, I haven't touched K'NEX in a year). </p>
<p>thank you :-)</p>
<p>I think I can upload instruction after Halloween.</p><p>Please be patient :-)</p>
<p>Wonderful!!!</p><p>Please upload instructions.</p>
<p>All right, I can think about it. ( sorry for my bad English :/ )</p>
<p>Hi, I've started to make instruction, but it's loooooooong...</p>
<p>I love it. This is a great project.</p>
