I was just messing around with my Knex & found a perfect way to make a Power Tower

I'd love to try out the Coaster Dynamix thing, but I've got too little funds and too many things higher on the priority list than a $500 toy...maybe someday down the road.

Rails: I used a bunch of orange connectors and green rods to create a rolling surface. Then to keep the wheels centered, I put yellow connectors and green rods together on each side of the orange connectors. I put these on all four sides of the tower.
Launch: To launch it I had to do a lot of adjusting, but in the end the launch looked really good and bounced. First, the tower was hollow with the exception of some white connectors for cords to run through, so the outer structure has to be real sturdy. The when building the gondola put some time of connector that are directly lined up with the running rail. At the top of the tower centered directly above the running rail there needs to be pulley. For the launch I used four elastic cords, that ran from the gondola up over the pulleys and down through the tower structure (the white connectors centers) to the bottom. I tied all four cords to a Big Ball Factory ball to create the tension.
The ball has to be able to move though, and hit a white connector when the gondola is that bottom of the tower. This is where the adjustments came to be a pain. The ball had to hit a white connector low enough in the tower so that the gondola would reach the top.
This took a long time to do, and in the end I couldn't get the car to fall all the way back to the bottom. So, it just stayed in basically the way they keep the gondolas on power tower sometimes, somewhere on the tower. However, it gave the most realistic launch and bounce in my opinion. I was working on a launch mechanism that was like TTD (sled) using elastic, but didn't have enough track tubing.
I wish I had pictures, because mine was about 6.5 ft. tall, and I built it about 4-5 yrs ago. It was definitely my crowning K'nex achievement.
