Sweet

I hope you can pull off those wingovers. Such a pia..

Who said I'm having any?

Not sweet!

 

[Uncle Arly]

Supporting is well underway...

 

[Xpress]

Hmm, that's an interesting bank angle there on the first drop turn. Most B&M inverts I've seen have more of a bank angle, say about 80*?

 

[Uncle Arly]

This coaster doesn't need that much, the forces are fine on the drop.

 

[Xpress]

^You still should go for it though, it'll probably ride better (and smoother)

 

[Antinos]

Xpress: there's no way an invert has around 80* banking in that flare at the top of the lift.

To be honest, your supports look more Vekoma than B&M. The horizontal beam shouldn't overlap with the diagonal part of the A frame. Instead, they should be flush, or close to it.

 

[Uncle Arly]

Sorry, what do you mean by that?

 

[Antinos]

Your supports look like this:

They should look like this:

See how they're not overlapping? They're 'cut' equal.

 

[Xpress]

^Well, it's not exactly easy to replicate the "cutoff". You can make it appear cleaner by making the cross tube like so.

OKAY.. maybee 70* then.. 70-80* though still feels about right for a B&M invert drop entrance

Sorry, Rollerdude, Xpress is actually right. Best I can do is make them as close as possible.

^Which you haven't done in that picture anyway..

Your lift hill supports should look much more like this:

^ Why?

The one he have done looks like those on Phaethon: http://www.rcdb.com/m/3935.htm?p=20362
The only thing he needs to do with them is to move the top piece flush to the brace (as stated before), and then change the support that holds the cat-walk so that it continues all the way to the brace.

 

[Uncle Arly]

Exactly, Loefet. They have to be like that due to the cobra roll. A few inverts have lift supports like that.

 

[Uncle Arly]

Well, I needed to take my mind of stuff, so here we are..

Better cut-offs on supports...

And the layout..

 

[Hixee]

Oooh, you've gone for the 'Jo-Jo Roll' before the lift. Nice touch.

Is there an MCBR, I can't seem to spot one, unless it's after the Cobra Roll.

Supports look much nicer too.

 

[Hixee]

Shoot!

Still need to fix the lift support a bit.

The top one should be tighter just as you have done on the other supports, and:

Thank you. Nope, no MCBR, I tend not to use them on Inverts, and I don't think this one needs it, it has nice pacing throughout, and a MCBR would ruin that.

Yeah, I wanted a Jo-Jo Roll for some reason. It's not taken very fast, but you wouldn't get much hang-time from it.

That was an old screenshot, all has been fixed since then =].
