The only reason I joined was to say this.
I am the previous record holder and I will let you know that Cosi, Michael and
I worked very hard on Particle Accelerator to push it's height to the max. I wanted to inform everyone that our 40 ft. was indeed free-standing, although
we used a cable to help with construction (to help make it more stable when we were placing parts on top) we took that off before we launched the car around the track and never putting the cable back on, there by making it free-standing.
And just to let you know, I was bashed about everything that was wrong with my coaster as well.
