Worlds Largest K'nex Loop: Test Launch 1 Successful!

video
I finished the runway and launch mechanism today and completed several dozen test runs with a 100% success rate! I was surprised at how little force is needed to launch the cars all the way through the loop, I built a 15 foot runway and it only takes about 3 feet of acceleration track to make it through. Here is a video both in real time and at 210 frames per second showing one of my test launches.

All that remains now is the return track. Construction will begin on that tomorrow.
