P. 403 - Park opening for a limited Holiday Event!

Recommended Posts

^The pre-drop isn't the section of track before the drop (Great Bear's helix, Mantis/Green Lantern turnaround, etc), it's the little five foot dip that retracts the lift chain, as seen on the inverts pre-2010ish, all standups, all floorless, sit down, etc. Great Bear's helix comes after the pre-drop, it's just an element before the drop.

I don't think there is a definition of "pre-drop" (If people say "Great Bear's pre-drop", I know what they are talking about), but I'm pretty sure that people on this thread mean something like what's on Raging Bull at Six Flags Great America

 

Look at the small little section right before it goes down the first drop.

And B&M seems to have stopped using pre-drops across the board. I'm not sure why that is.

 

I think the term we are looking for isn't "pre drop", I've always called it the "B&M Dip".

 

I can only speak about what I know. That said, I think it has to do with the number of chain dogs that are engaged.

 

Random Coaster Nerd Fact:

Each train on Banshee has 1 chain dog which is right above row 2, however they have 7 anti roll backs. The weight is relieved from the chain once half the train has crested.

 

On most coasters you can hear the chain dogs bouncing on the chain as the train begins to speed up. I think this is the stress B&M was trying to eliminate from their earlier designs.

I like the pre-drop on Raging Bull because it gives you a little more airtime while going down the drop. I wish B&M still built coasters with pre-drops, but now that they've worked out the kinks with the lift chain, they aren't needed anymore .

Interesting. I had no idea each train only had 1 chain dog. So I suppose that its location has an effect on "how far" the chain goes on the top of the lift.

It makes sense now that I think of it. Leviathan's (and Fury's) chain are the ones that end "the earliest" on the top of the lift probably meaning that the dog is further back than on banshee which should explain why those are the only two where the chain catches the train so early. (I think)

I've heard from a book that they only use pre-drops now on drops that are curved.

 

This was true for a period of time, but since the late 2000s the only B&M built with a pre-drop has been Hair Raiser. OzIris, Nitro (Adlabs Imagica), Banshee...they all have curved drops and lack a pre-drop. I'm not entirely sure what changed with the design (probably something with the chain dogs), but B&M has decided they are no longer necessary. While I still like them on B&M's smaller coasters, having one on a hyper is pretty awkward and just doesn't feel right, so I'm glad they've been eliminated from those designs at least.

I'm also glad that predrops are disappearing from B&M hyper coasters, as they seem to make a very awkward transition into the drop. What kinda book did you read that in?

 

I am pretty sure it was a coaster book from 2006.

Okay, so this gives us somewhere between three and seven days to prepare for the onslaught of comments about how slow it looks based on the first run. I think that's enough time.

 

Judging prior to riding is how we do things.
