I'm trying to make a multi-directional launch like on Tempesto and Superman Ultimate Flight (SFDK), technically known as a Premier Sky Rocket II. I only knew about those two coasters, but there's actually 4 clones currently open and 2 more under construction.
If I get this to work, Jumpge is planning to copy my design and turn it into a full recreation. I'd like to build the entire model myself, but I won't have enough time while I'm home from college.
So my first attempt is an utter fail. The gears allow me to switch the direction of the chain without stopping the drill motor. The gray gears slide back and forth, alternating which one is in contact with the central red gear. On the track, I disconnected some of the middle tubing so that the chain rubs on the bottom of the train to propel it forward or backward. However, the drill just isn't fast enough, so I'm going to need to use some other means of propulsion. Most likely surgical tubing

That's all for now. Merry Christmas!
