This was posted 12-1-02 meaning he either has had two screen names all along or ThunderFun isn't him and he's still out there some where.
...Or maybe that's what he wants us to think! CPNut is playing mind games with me.
I'm going to say that isn't CPnut. Just a person with the same level of intellect. This guy almost sounded smarter than CPnut, and there were no creepy stalking comments ;)
Perhaps he finally got the clue after getting booted more than 5 times? I don't know.... We can only hope....

Heres my out take on this ride...
Rollercoasters are built to be scary and appear dangerous.
This ride even has us enthusiests saying it looks too dangerous! I think Vekoma succeded
Darn! if we get this worked up over this ride, then I can only wonder what the General Public thinks...
I don't think much of it to tell you the truth.

Is that a Q-bot in your pocket or are you just happy to see me?
Mabye Cedar point nut/seeder point/Chris Sawyer IS thunderfun, but TRYING to act smart.

Two friends, extremely in love with the same girl. She hates them both, but likes a third friend. (You think I'm advertising a reality show? That's my life!)

I think he's gone, once and for all. It's time to let that joke go and move on.
Very interesting coaster I might add! Now if only I could get stuck verticle........

That is, the catch won't release...in fact, can't release...until the track is lined up and locked into place.
At least that's how I would do it...
I'll just go ahead and back up the almighty RideMan ;)...
There are pictures on ECC website: http://www.coasterclub.org/en/fd/53/gmax.shtml. I've talked about the 'failsafe' mechanism on this ride before. You can see quite clearly (or blurrily, as the case may be) in those pictures, the device located at the front of the tilting track. Sailors and mountaineers (incidently two of my favorite sports, but my experience is weighted towards climbing/mountaineering) should recognise something that resembles a cam. For instance in small boats, you've got the cams that hold down the jib. In climbing, you've got cams which are expensive pieces of equipment for trad climbing, which are much more useful than hexes or other similar anchors.
Basically, you've got a system that tightens more and more under load. Provided Vekoma used the right strength of steel and whatnot (which believe me, no matter how much you hate Vekoma, they did). To ensure absolute safety, there would be some mechanical system to release the catch, which can only be done from the vertical position. If I were you, I'd probably be more worried about being stuck vertical over flying off the track into the ground below.
I think if Vekoma can sell more of these things, move over Boomerang - if you want a something that people would just crowd around and watch for hours on end then this is the man for the job.

So what if the best coaster in Australia is a second hand Arrow?

Duh, of course they would if they what to make money. They could most likly careless about safety. The brakes could most likely not hold the train if the power went out. Even if it does it can't hold the for more then 5 hours.
DUH, of couse you are really dumb. think of it this way. Power is needed to hold the brakes OPEN not closed. They are held shut by high power hydrolic rams or high air pressure on most modern steelies and they will not fail in five hours. I would say that the loss of enough pressure to cause them to fail would likely be months and then some.

That's right. All brakes are closed by default, and power (thus hydraulics / pneumatics) is needed to open the brakes. Very effective actually.
Concerning the future of the tilt coaster: Vekoma went to great extent in trying to sell their tilt coaster at the IAAPA. I'm still waiting for some kind of confirmation that they actually did it.

Dutch Coastin' :: European coasters, thrills and theming!
Contrary to what has been posted here, all the Vekoma brakes I have seen are pressure-applied. That is, system air pressure is needed to close the brakes. Air is provided to redundant brake calipers (that is, more calipers than are required to hold the train) by redundant pressure cylinders located at the brake run (that is, not all of the brakes are fed from the same reserve tank). Electrically, "closed" is the default brake position, but there has to be air pressure, so if electrical power is lost, the brakes will close, under reserve pressure from the air tanks (as a loss of power probably means a loss of air compressor as well).
I don't know of any incidents on any Vekoma or Arrow coasters where a single point failure has allowed for a brake failure. I know there was a station collision on an SLC as a result of a power failure once, but I suspect that was related to the loss of braking force in the advancing motors (without power the advancing motors might free-wheel), not a failure of the pressure-applied brakes.
Lest you think pressure-applied brakes are somehow unsafe, let me point out that every road vehicle (car, van, truck, bus) uses pressure-applied brakes.

Well, nobody said I was an expert on coaster brakes anyway. But as a mechanic I've experienced more than my fair share of automotive brakes. I believe them to be quite safe when used properly ;)
Same goes for coaster brakes as long as they're implemented properly. I mean all the brakes in the world aren't going to help if for some reason they stop working. That's why regardless of pressure-applied or the opposite (sorry, can't think of the term), there's some kind of system to keep them working during a power loss.
